This does NOT refer to the 1x wagering requirement (this is covered in clauses 3 and 4 of our T&C), but refund requests such as this one. The clause is very clear: funds have been used to place wagers, so we fail to see why the user would be eligible for a refund. Particularly considering that they have, almost certainly knowingly, broken the rules by betting using a certain technique that would give them an edge, no matter how large or small or whether they admit it or not.
So, what are you expecting from a player to do after making a deposit on your casino? It is obvious that a player will use his deposit to place bets. OP could be guilty here for using any techniques to make sure profit from his bets. But confiscating the deposit by creating such unfriendly rules is an alarming thing. @OP, the chance is almost zero for you to get the refund of your deposit. Every casino takes the action according to their terms.
