Lucky Nugget Casino - Stalling on account verification and withdrawal

20 days ago I put in for a withdrawal with Lucky nugget casino. I got an email back saying my banking is incorrect, and they also refunded my withdrawal back into my Lucky Nugget account. This is what I got back from them: Kindly note that we are unable to process your withdrawal to you due to the following:
Your bank account details are invalid. Please select an alternative banking option or confirm your bank details (through bank statement or voided cheque).
Since then I have sent them (in an email) My voided cheque, 3 pictures of various credit cards, my drivers license, my SIN card AND a recent bill sent to my home address. I also downloaded all these documents on my profile on the casino. I have since gone through this exact same thing with them "7" times since then. I have gone on their instant chat (Because that is the only way of talking to this casino) 7 times as well. Each time I have been told that my inquiry has been escalated. 4 days ago I once again was on instant chat with them...I was assured this would be the last time, and my withdrawal would go through now. This morning I got the exact same email (for the 8th time) and the withdrawal is once again back in my account. I have been gambling with this casino AND all other Belle Rock casinos for MANY YEARS. I have not had this problem before.
