Appalling casino

Appalling casino. 24/7 help isn’t available ever and they don’t respond when using the contact us email system. Accepted a deposit and let me play a bonus then refuse to let me place any bets saying limit reached. They now have my money and want me to cancel my bonus winnings to withdraw my money. Absolute scam of a site. Avoid and use more legitimate sites. Also give bonuses which don’t work then refuse to issue them saying it’s not policy to issue bonuses your unable to use

I am waiting on a withdrawal of £30,000…

I am waiting on a withdrawal of £30,000 (plus the £5 admin fee that I had to pay!!!) since last Wednesday afternoon. Yes, thirty thousand. Can I get a meaningful update anywhere? Nope. Live chat giving me the runaround. No straight answers. I have uploaded all of my documents and these have all been approved so I’ve done my part. So frustrating not being able to talk to anyone and there is one agent that disconnects when he can’t be bothered to answer your questions anymore. Disgusting treatment. PAY ME MY FAIRLY-WON WINNINGS PLEASE. Site says 0-6 days for payout AFTER cash out is approved - mine is still pending after all this time

4 days of withdrawal pending and emails being ignored until I gave an ultimatum that they have had a more than reasonable amount of time to pay me. I gave them 2 hours to pay or I'll be adding daily interest and legal fees. Still no email but my money was swiftly deposited into my account within the hour.

You need to avoid this site completely

You need to avoid this site completely. I've had my account closed after trying to withdraw my money . I was in contact with them through live chat a few times and when they couldn't resolve my issue they would end the chat on me and now my account is closed and they owe me 150.00 and they aren't replying to my emails .... so frustrating and they are so rude.

Not trusted

Had no problems with payouts in past always in bank within hours. Latest win is still pending many days later. Documents requested and sent and still nothing. No replies to email. No live chat. Not able to telephone. Really disappointed in this site...

Hi John Plumb

We know a poor session is frustrating - but gambling is a game of chance and positive results can never be guaranteed.

As a licensed UKGC operator, our games are tested rigorously for randomness - and we always aim to launch games with the highest RTP possible.

Withdrawals are an ISSUE‼️‼️‼️

15 May 2025. (23.09)
Having had to wait 2 weeks for my withdrawal in February, I’m been given the run around yet again!!! I’ve managed to deposit and withdraw several times after my ordeal in February, but it seems to be an issue when it’s a slightly bigger amount!
NO response to emails, having to upload the SAME documents from February (when I was told my account was verified and would not need to upload any more documents)! Live chat not working!!
This is very FRUSTRATING!!!!

Please now address my withdrawl!!!

I will continue to post until this issue is resolved!
I honestly hate doing this but this is NOT ACCEPTABLE and very POOR customer service!!

SOMEONE PLEASE REPLY TO MY EMAILS‼️‼️‼️‼️

16 MAY 2025 ‼️‼️‼️‼️
(12.03)

Still NO RESPONSE!!!!

TWELVE emails later!

Please at least acknowledge my emails!!!!

NOT HAPPY!!!!!!

I have played on a number of site before but i truly feel like this is one of the better ones, depositing and withdrawing have been so easy and i have even had a few decent wins, unlike some other site that seem almost rigded, with no wins and no payouts, just pointless offers. Highly recommend

Second withdrawal took little longer then hoped

Good site to play and I have got all the bonuses and also have won which is positive although when it comes to withdrawas my first withdrawal was fast and after that it did take quite a bit of time to receive but most importantly I did receive it. thank you

These parasites are 100% fraudsters even their support is nonexistent and one of their email addresses for the company that actually owns the site goes to a completely different company who have put a note on their website saying this company has no connection to them and to contact the authorities if they have been scammed by them...
