Welcome to the scam
you can ask OP to investigate this thing and get comp and refund, OP is nice and this site is nice too.
I don't think it is a scam casino, they have paid lots of comps and bug bounties for players, a good one, connection or server errors are normal, you can find this issues in other casinos.
