This page explains how to reach the Top Mastercard Casinos editorial team and what to expect when you do. We compare online casinos that accept Mastercard for US readers. We are an independent comparison site, not a casino, so we can't see or change anything in your casino account.
Players must be 21 or older (or the legal gambling age in their state). Gambling involves real financial risk, and no site on this page can guarantee winnings. If gambling stops being fun, see our Responsible Gambling page or call the National Problem Gambling Helpline at 1-800-GAMBLER (1-800-426-2537).
What you can contact us about
- Corrections: a bonus term, payment detail or licensing note on a review looks out of date or wrong.
- Review feedback: you think we missed something that matters when comparing Mastercard deposits, withdrawals or wagering rules.
- Site questions: how our ratings work, or how to read a comparison.
- Business or media inquiries: questions about how the site operates.
Please include the page address, the detail you are questioning and, if you can, where you saw the updated information. That lets us check it faster. We verify facts against the operator's published terms, and we date-stamp each page with its last update.
What we can't help with
Some requests belong with the casino, your card issuer or a regulator. We can't resolve these for you:
| Problem | Where to go first |
|---|---|
| Declined Mastercard deposit | Your card issuer, which can tell you whether it blocked the charge, and the casino's support team |
| Pending or missing withdrawal | The casino's live chat or email support, using your account and transaction details |
| Bonus not credited or wagering dispute | The casino, with the bonus terms you accepted in hand |
| Unauthorized card charge | Your card issuer, promptly |
| Licensing or fairness complaint | The casino first, then the gaming regulator in your state, where one applies |
We don't process payments, hold funds or act as a go-between with operators. Never send us card numbers, passwords or ID documents. We will never ask for them.
Before you contact a casino about a payment issue
- Note the date, time, amount and the last four digits of the card used.
- Screenshot any error message or confirmation.
- Check whether the bonus terms limit card deposits or payout methods.
- Contact the casino's support first, then your issuer if the charge is unresolved.
Card declines can come from issuer restrictions on gambling transactions, so a failed deposit doesn't always mean a problem with the casino. Availability can also vary by state, so verify that an operator accepts players where you live.
How we handle your message
We read the messages we receive and use them to improve our reviews. Because we don't hold your casino accounts, we can't give account-specific answers, and we can't promise a reply time. We don't offer legal or tax advice. For questions about your legal or tax position, consult a qualified professional.
Independence and commercial disclosure
Top Mastercard Casinos may earn a commission when readers use links to some of the casinos we feature. That doesn't buy position: rankings rest on our research into banking options, terms, security, game range and support. Read more on About Us. Bonus conditions, such as wagering requirements, can change, so check each operator's official terms. Our own Terms and Conditions cover use of this site.
