Hi, I'm not sure if I'm in the right place. I've been trying to make a withdrawal from 21dukes for about 6 weeks now. Each time, I've put in a withdrawal request, they request more documentation. This is now my 3rd request to withdraw my funds and they are asking me to complete a voucher with all my credit card details in addition to a bank statement for that card, plus a picture of the front of the card. I'm not sure if this is correct, can someone help please.
