My Withdrawal request is timestamped with August 31, 2021. So I absolutely did make the cut off. I PM'd BetBTC but haven't received a response. I wrote to see if anyone else is in the same boat.
I checked their Help desk and it's already closed , i checked OP's account he has not been online since September 3 , actually he had not updated since the last post he made prior to the last day of withdrawal.
lets hope that he'll gonna be online again because there are no other available communication from this site but the OP Himself.
though he cleared that he give a chance to the last withdrawal midnight of september 1 yet he had not make confirmation here not like what he does before His last post in which updating all pending withdraws.
