I haven't Deposit and claim 100% bonus. I think better wait from OP explanation for this problem.
Have you ever asked directly on their live support about this oddity, especially you still have screenshots as proof of these bugs, because it seems that waiting for their representative to be online in this forum will not know when he will be back, just curious. This is indeed only free credits but maybe these bugs can happen to players who activate the deposit bonus and will be a problem for the casino.
He should ask in online /Live support if you have any problem with deposit /Withdrawal or others reason. all legit site will reply him instantly within 5 minute. and help him as well. He just has to mentioned all right things . Then he will get his solution quickly. This is a very simple matter. There is no reason to be afraid of it.
