Can anyone help with CSTONLI or DIGITLID.
Interestingly the latter shows a residential address on my csv bank statement and when Google it has about 10 random businesses none of which are gambling sites.
I've relapsed and spent 6k in a week. My bank hasn't flagged it and has allowed to continue. My own doing I know 😢
I think we're talking past each other a bit – possibly because of the automatic translation in the forum. I'm deliberately writing in German because nuances are easily lost with English/auto-translate.
Regarding "Contact at Mastercard":
Even if someone knows someone at Mastercard, this offers you, as a cardholder, virtually no practical advantage. Mastercard/Visa don't "block" your chargeback – what matters is whether your issuer (your bank) actually submits and pursues the dispute/chargeback. The scheme is primarily a set of rules/network/arbitration body between the participants.
Contract & Fees:
As a cardholder, you don't have a direct contract with Visa/Mastercard. Your debit/credit card agreement is with your bank (issuer). Scheme/interchange fees are handled by the merchant/acquirer and distributed within their system – this isn't a fee you pay directly to Visa/Mastercard for each purchase. You may pay bank-related fees (card/account fees, interest, FX fees, etc.), but that's separate.
Consumer Duty/Gambling Block :
It's difficult to fault a bank for not stopping gambling payments if the transaction wasn't identifiable as gambling due to incorrect MCCs/descriptors. A gambling block can only be technically effective if the transaction data correctly identifies the category. Therefore, the crucial question is where the misclassification originates (merchant/acquirer side) and what the bank can realistically influence. It would be like receiving a parking ticket when the car was demonstrably parked in the garage: It's difficult to establish a "breach of duty" for something that was objectively neither detectable nor controllable.
Chargeback expectation:
Assuming that you can get everything back via chargeback after gambling shifts the focus away from the real issue: The known problem needs to be addressed, not retrospectively "technically fixed." Accordingly, in practice, correctly authorized gambling transactions (MCC 7995) on Visa/Mastercard are often only very limitedly susceptible to chargebacks – otherwise, the systems would be constantly flooded in such cases.
Incorrect MCC:
In the scheme rules, an "incorrect MCC" is more of a compliance/data issue than an automatic "cardholder refund button." With Visa, this can only become relevant as "invalid data" in specific situations (e.g., if demonstrably incorrect data led to authorization or an MCC mismatch exists); with Mastercard, this often involves (pre-)compliance/acquirer issues rather than a traditional cardholder chargeback. In short, an "incorrect MCC" can have consequences for the merchant/acquirer – but it doesn't automatically mean that all past losses will be refunded.
And personally, because you mentioned addiction:
I respect your efforts to get clean. But even if refunds were available, money alone won't break the cycle. Crucial are protective mechanisms (blocks, limits, self-exclusion) and genuine stability – otherwise, a "refund" quickly becomes a "trigger" again. I don't mean this as an attack, but rather as a reminder of a pattern that, unfortunately, is all too common here.
In the end, it's quite simple:
UK law only mandates refunds for "unauthorized payments." Authorized but disguised gambling payments (e.g., incorrect MCC/descriptor instead of MCC 7995) do not automatically trigger a refund. Instead, it's at most a matter of scheme dispute/compliance issues and whether the bank conducted a fair review and responded appropriately. Unfortunately, the bottom line remains: if the payment is authorized, it's authorized, regardless of the true reason.
My tip:
Trying to "recoup" losses keeps many people trapped in a vicious cycle. Instead, use this time to become gambling-free – health and life are irreplaceable.
