Use the PAB service, there is enough to make it seem that incompetent CS mislead you into doing something you should not have done, and this was only possible because of a technical failure that was mishandled by the CS agent, resulting in the wrong advice being given.
The crediting of the bonus is very odd, since the deposit was not there, and this to me looks like some kind of technical failure.
The correct advice for CS to have given would have been to wait until the problem had been resolved, and the deposit credited BEFORE commencing play.
The "abuse" is that you have played and won with the bonus, but the casino didn't have your deposit in your account, so you could never have lost had play gone against you. You had a chance to win, but the casino didn't.
