Actually the fault was yours - of course, but I see you admitting the mistake. The casino may have the right to refuse your request regarding the transaction - but it would probably be wiser if they resolved your problem manually. I've never come across a similar case before - but hopefully you can get your $111 back or at least they fund your account with the same amount.
I'm not sure you'll make it - but hopefully you get it back. My question to betpanda - is it possible to refund this or at least you fund that user's account with the same amount?
I don't have the knowledge to be the judge here, while BetPanda hasn't specified if they can actually gain access to these funds in any way, logfiles mentioned that they may have access but the risk of compromisation isn't worth it. Apart from that, I'm confident that Betpanda will eventually honor the request and deposit the money to Woodie's account, either in full, or at least partially, since it's his fault for mistaken deposit. Even if it's not their fault, it's good publicity to the casino, even though in reality they aren't required to honor it.
Anyway, we shall wait for an official response from Betpanda, till then, I wish Woodie good luck.
