A Cardio Highlight charge on your bank or credit card statement comes from a third-party payment processor that bills on behalf of other websites, most often digital subscription services. The descriptor may appear as “CARDIOHL.COM,” “CARDIO HIGHLIGHT,” or “CardioHighlight.com,” sometimes with a phone number or reference code attached. Two things could be going on: you signed up for a subscription (often after a cheap trial) and the recurring billing has started, or your card information is being used without your permission. You can stop the charges by canceling through the processor, and if that fails or the charge was never authorized, you can dispute it with your bank.
Is It Your Subscription or Fraud
Before you do anything else, figure out which situation you’re in, because the response is different.
The most common legitimate explanation is a digital subscription you signed up for, possibly during a low-cost trial that automatically converted to a full monthly rate. The sites behind these charges tend to be adult entertainment platforms or niche content services. Because you agreed to the terms at signup, the processor treats each monthly charge as authorized. Federal regulations require that the terms of any preauthorized recurring charge be “clear and readily understandable” before your card is debited,1Consumer Financial Protection Bureau. 12 CFR 1005.10 – Preauthorized Transfers though in practice those disclosures are often buried in the fine print.
The other possibility is that you never signed up for anything. Reports from consumers suggest charges from CardioHighlight.com are sometimes tied to compromised card data processed through self-registered merchant accounts. Some people have traced unauthorized charges back to social media scams disguised as car giveaways or prize promotions on Instagram and Facebook. Amounts in these cases are frequently in the $49.99 to $59.99 range.
The fastest way to tell the difference is to search your email, including spam folders, for any welcome message or signup confirmation from an unfamiliar site around the date of the first charge. If nothing turns up, treat the charge as unauthorized.
How to Cancel Through the Processor
If the charge came from a subscription you actually created, canceling directly through the processor’s website is the cleanest path. Most billing portals linked to these descriptors have a lookup tool that asks for a few pieces of information to pull up your account. You’ll usually need:
- The transaction date and amount from your statement.
- The email address you used when signing up.
- The last four digits of the card on file.
- A member or transaction ID from the signup confirmation email, if you still have it. Most portals can find your account with just the email and card if the ID is missing.
Once the system locates your account, select the cancellation option and finish the form. You should get a confirmation email within 24 hours. Save it, and screenshot the confirmation screen. If a dispute comes up later about when you canceled, that’s your proof. One thing that trips people up: entering a different email or card number than what’s on file makes the lookup fail, and the subscription stays active through the next billing cycle while you sort it out.
How to Dispute the Charge With Your Bank
If the processor’s website won’t cancel your subscription, if you can’t locate an account at all, or if the charges were never authorized, dispute the charge through your financial institution. The rules differ depending on whether the charge hit a debit card or a credit card.
Debit Card Disputes
For debit cards and other electronic fund transfers, federal law gives you 60 days from the date your financial institution sends the statement showing the error to report the problem.2eCFR. 12 CFR 1005.11 – Procedures for Resolving Errors Missing that window can limit your rights, so don’t sit on a charge you don’t recognize.
Once your bank receives your dispute, it has 10 business days to investigate and determine whether an error occurred. If it needs more time, it can extend the investigation to 45 days, but only if it provisionally credits your account within those initial 10 business days.2eCFR. 12 CFR 1005.11 – Procedures for Resolving Errors The bank can hold back up to $50 from that provisional credit if it has reason to believe the transfer was unauthorized. If the investigation confirms the error, the credit becomes permanent within one business day.
Credit Card Disputes
Credit card chargebacks follow the Fair Credit Billing Act, which requires creditors to acknowledge billing complaints promptly, investigate billing errors, and refrain from actions that hurt your credit standing while the investigation is open.3Federal Trade Commission. Fair Credit Billing Act You generally have 60 days from the statement date to notify the issuer of a billing error in writing. The issuer then has two billing cycles, up to a maximum of 90 days, to resolve the dispute.
Whichever card you’re using, documentation strengthens your case. Bring the confirmation number or screenshot from your cancellation attempt, the statement showing the charge, and a written explanation of why the charge is unauthorized or erroneous. Banks handle these disputes routinely, but clean documentation means fewer follow-up requests and a faster resolution.
If the Charge Looks Like Fraud
When the charge is genuinely unauthorized rather than a forgotten subscription, disputing a single transaction isn’t enough. A compromised card number can be used again, so close the door instead of only challenging one charge.
- Call your bank and request a new card number. That immediately invalidates the old one so no further charges can go through.
- Review at least 60 days of statements. Fraudulent charges rarely come alone, and small test charges (sometimes $1 or less) often precede the larger ones.
- File a report at IdentityTheft.gov. The FTC’s system generates a recovery plan and creates an official record if you need documentation for your bank or law enforcement.
- Pull your free credit reports at AnnualCreditReport.com. If your card data was stolen, other personal information may have been too, and unfamiliar accounts on your reports are a warning sign.
Watch for Overdraft Fees and Interest
An unwanted recurring charge on a debit card can do damage beyond the charge itself. If the subscription debits your checking account when the balance is low, you may get hit with an overdraft or non-sufficient funds fee on top of the unauthorized amount. These fees can run up to $35 per occurrence at some banks, though many institutions have reduced or eliminated them in recent years. When you dispute the underlying charge, ask your bank to reverse any overdraft fees that resulted from it. Most banks will waive those fees when the triggering transaction turns out to be unauthorized.
On a credit card, the risk is different. An unnoticed recurring charge slowly eats into your available credit and accrues interest if you carry a balance. Catching it early keeps both the direct cost and the interest to a minimum.
Trade-Offs of a Chargeback
Filing a chargeback is your right, but a couple of side effects are worth knowing. If the subscription is one you actually used before deciding to cancel, the merchant may ban your account from their platform permanently. Some processors also share data across their merchant networks, which can flag your payment information for future transactions with other sites using the same processor. None of that should discourage you from disputing a charge you didn’t authorize or one the merchant refuses to stop. But if you simply want to end a legitimate subscription, canceling directly through the processor first avoids these complications and is faster than waiting for a bank investigation to play out.
