He didn't make any deposit. He won that money from free spins which makes me wonder if he has completed the wagering requirement before he made the withdrawal request!
he said the LTC has been transferred but nothing arrived in his wallet. so I assume that the wagering requirement was met and that's why the request was approved. the OP's case would be easily understood if he can just provide the necessary evidence supporting his claim and properly explain what exactly happened.
my payment history shows that the LTC have been transferred but I have no other indication except that nothing has ever arrived in my wallet
