I remember similar situation happened to one of Luckiest user which I read on their announcement thread. AFAIK, he also forfeited the bonus he claimed when he made his first deposit. However, it is stated in their terms that once the bonus has been claimed, all winnings will be considered as bonus money. And if ever the bonus was forfeited, all bonus money will also be gone.
I don't say that it's the same with Frogbet, but maybe their terms have something that could explain what happened here. If none, then maybe it's a glitch. Though, it's less likely to happen only to one user. But since you have already contacted the support, I hope the issue you have encountered will be sorted out asap.
Fortunately for me it wasn't a deposit bonus & this was manually applied..and btw I didn't play through any of the funds (2cents).
If this is the model the casino is running then it's a big red flag and needs to be fixed, or the the minimum separate real funds from bonus funds !!
UPDATESo these funds were returned to me as bonus funds with terms like maximum bet of $10 and casino games kept my wager only winnings were paid out ,so any dice game say of $10 * 1.02 odds means I get 2cents from that and lose the $10 wager . Anyway long story short lost my funds that I legitimately won to the system issue . Not happy with this experience not 1 bit @&#
