Update:
So I spoke with my payments department and the payments issued were bank drafts and not checks, so they are definitely not “bouncing.”
The only reason I can think of for the returns are that banks are refusing to process these international drafts for reasons I have no idea.
In any case, any individual whose draft from Casino Coins was returned please contact me ASAP and a new draft (from a different bank) will be issued immediately.
Cheers,
Nick
