Nationalbet 

No stars
Scam site.
Deposited several times, three occasions payment came up as pending but didn't credit my account however money was taken and showing pending in bank account.
Spoke to live chat they advised me these were failed payments and would go back into my account.
Also received email stating payments unsuccessful please try again.
The £60 didn't go to my bank, it went to national bet and my account was credit 12 hours after depositing.
I've tried to withdraw this however they won't verify my account no matter what documents I've sent .
Customer services a disgrace.
Please don't use

Guys, please don't. Just don't. I too searched for sites that allow gambling when registered with gamstop... and found these crooks. They allow you to deposit unlimited amounts but you CAN'T WITHDRAW. I deposited thousands, and when I tried to withdraw £150 that I won on a sports bet they make it impossible to do so. Live chat will give you the run around, every document you send them isn't good enough. They will put you through hell... please guys. Don't be sucked in. See out your self exclusion period and try to live life, these vermin aren't even UK based, what they are doing is completely illegal and unethical. I hope this review saves someone. As for Nationalbet / Nationalbet10 / 20 however many sites you have, you are filth.

you don't get any bonus, it's a complete scam...the worst casino.

Serious Warning Regarding Nationalbet1.com

Nationalbet1.com has been reported for highly dubious and potentially fraudulent practices. Multiple users state that the platform systematically blocks all withdrawal attempts, even after full identity verification. The casino then demands an apostille—an unnecessary and costly document authentication process often exceeding €350—which appears designed to deliberately hinder payouts.

These actions suggest a deliberate strategy to avoid honoring legitimate customer winnings. The terms and conditions cited to justify such behavior are arbitrary and unreasonable. Despite these serious concerns, the licensing authority continues to allow the platform to operate, raising further questions about oversight and consumer protection.

Customer service has been described as entirely uncooperative, with staff appearing to actively assist in these practices. Based on these accounts, users are strongly advised never to register or deposit funds at this site.

Nationalbet1.com exhibits strong indications of fraud and may be operating in violation of consumer protection laws. Legal and regulatory action should be considered.

SCAM!! Don’t waste your money. You can deposit no problem but absolutely impossible to withdraw I’ve sent all my proof of id and proof of address there now asking for tax returns and all sorts

By far the worst gambling site ever used!

Please stay away - borderline illegal!

Deposited £600 and had roughly £4,600 winnings allocated against my bonus pool. I needed to stake another £4000 to claim the bonus funds. They then withdrew my ability to make any bets and are not responding to any correspondence.

They are just delaying the bonus pool so my winnings expiring. Emailed everyday and they are honestly absolute scumbags!
