According to our terms and conditions, you can use only 1 no deposit bonus to try out our games. Your last winnings were from 10th no deposit bonus that you took (BEGADO30).
Unfortunately your withdrawal request cannot be approved as it violates our terms and conditions. You are welcome to take advantage of special offers, take free chips for your deposits, play with huge match bonuses that we offer and cash out your winnings from them. You just need to contact our customer support for assistance and they will provide you with all necessary information how to get a free bonus, however, you are not allowed to use no deposit bonuses that you find on forum for non depositor as you've already used 10 (when you could take advantage of just one).
I have sent an explanation to askgamblers for review.
