You have probably done this. A charge you did not recognize shows up, somewhere between $20 and $60, from a company name that means nothing. You call the bank, you get the money back, you forget about it.
Here is what nobody told you. That dispute was not just a refund request. It was a data point, and it was supposed to set off an alarm somewhere above your bank. Last week the FTC described a company that got paid to keep that alarm from ringing.
The company is Humboldt Merchant Services, legally 5967 Ventures, LLC. A payment processor sits between a merchant and the card networks and decides who gets to charge your card at all. The FTC says Humboldt gave that access to more than 1,000 merchants that were shell entities, fronts for companies running unauthorized billing scams, including the Legion Media operation the agency shut down in 2024.
The chargebacks came in exactly as you would expect. Almost 10 times higher than the level the credit card brands treat as excessive.
That number is not subtle. That is the system working. Thousands of people noticed a bogus charge and said so, and the rate climbed to ten times the threshold that is supposed to get an account cut off.
So what happened? According to the FTC, Humboldt moved the accounts. It put high-risk merchants on bank identification numbers coded as low-risk, the first six to eight digits of a card number that tell the network what kind of account it is dealing with. It spread the volume around so no single account tripped a monitoring threshold. The industry calls that load balancing. Translation: the alarm still rang, and somebody re-wired where it rang.
The money explains the effort. By 2017, the FTCβs filing says, this line of business was roughly 80% of Humboldtβs profits, and profits that year topped $80 million.
Humboldt pays $12 million for consumer redress and is permanently banned from processing for shell companies, merchants on the card networksβ MATCH list, merchants under law enforcement action, and new e-commerce outfits whose only address is a mailbox. The court entered the order on September 11.
Now the part that is actually yours.
Your dispute is evidence, and a phone call is weak evidence. Under 15 U.S.C. 1666, a written notice of a billing error, delivered to the address your issuer names for disputes inside 60 days of the statement, starts a clock the bank cannot ignore: 30 days to acknowledge in writing, two billing cycles and no more than 90 days to resolve, and no collection on the disputed amount in the meantime. A call gets you a provisional credit. Writing gets you a record.
Do this now. Open your last three statements and read every line under $75, because that is the range these operations live in, priced low enough that most people eat it. Anything you cannot place, dispute it in writing, not just by phone. Then report it at reportfraud.ftc.gov, because that is the file regulators actually count.
And if you hear about Humboldt refund checks: the FTC does not charge you to receive one. Anybody asking for a fee is running the next scam.
Small charges are not too small to fight. Ten times the excessive threshold is what it looks like when people fight and the fight gets routed around. If a mystery charge is riding on a card you are already carrying a balance on, run the real cost through the debt payoff calculator, and if the card itself is the problem, start with the credit card comparison.
