Crystal Slots Casino Complaints

I joined Crystal slots 2 week ago . I won £4000 which took ages to be able to withdrawn . I finally received the withdraw and place £1000 back on to try my luck . Crystal slots froze my account as soon as I deposited. I received an email asking around my affordability and asking me to send 1 payslip and 3 bank statements. I did this on Monday 23rd January. Their email stated they needed to verify my account ( I have many emails stating my account is verified) and this would take two days. I have received no emails in return and my account remain frozen with a £1000 stuck in my account . I am not able to play or withdraw my funds. I have emailed several times around sending my information and do not get a response .

Hi I made a withdrawal on the 30/06/2020 I have sent all my verification over and signed up to gamstop for 6 months.
Crystal slots are telling me my withdrawal can not be processed due to my bank rejecting the withdrawal deposit, this is not true and I have checked with my bank 2 times and they have said they do not block money coming to my account under any circumstances. I have sent multiple follow up emails asking what are my other alternatives etc.. But still no response for 5 days. It clearly states they will reply within in 2 business days but I've been waiting since the 03/07/2020 and have no had a response, I sent another email on the 06/02/2020 and still no reply about withdrawal.
