Withdrawal not paid yet

I have for the past few weeks been trying to withdraw my winning from sinspins casino, however everytime I attempted to process the withdrawal via bank transfer I am informed to cancel this and process it through card withdrawal. I have send them all the requested documents with an additional letter proving that I no longer have a bank card and that is why I have to process this via bank transfer, however they just send me the same thing cancel the withdrawal and process through card. I cannot contact them Via phone and they only email me a maximum of once a day I am completely lost with what to do Edward < surname removed >

I won £90 on the 17th September and after sending in my ID it was processed on the 21st September, i still haven't received this payment. I have contacted them on a number of times, first being told that it was processed on the 28th and should be in my bank within a few days. Then i was told that there was a problem with their credit card company they use which has resulted in late payments. It has been almost three weeks and still no payment has been received. I have also emailed them asking for them to make a fresh transaction of £90 and for them then to trace up what happened to the original transaction without a reply. I have tried and tried to sort this out between me and Sin Spins but have been left with no choice but to write a complaint on here.

I deposited two days ago and my account was immediately locked. They requested documents and current card I used so I sent them what they asked for. This was no problem. They then sent an email requesting the last three credit card I used and the credit card statement showing the transactions. I told them I could not provide that because I only use prepaid visa or mastercard vanilla cards. Once you use it to deposit and there are no winnings resulting from the money then you throw it away. They are a one time use. I have told them that numerous times via email. Most Canadian credit cards do not allow deposits to international gambling sites. I have also requested that security call me to no avail. I asked in another email to either unlock the account or refund my money and again no response. They must of come across this before and I don"t understand their problem. They just keep sending emails requesting the last three credit cards and all I could provide is the one I used two nights ago and that is a prepaid mastercard as well. They have good reviews so I don't understand their problem. Please help me resolve this issue.
