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 the SAME documents from February (when I was told my was verified and would not need to 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
