How long does your pending withdrawal still on processing status. You should clarify complete detailsmof your case because your statement doesn't make sense. Probably its due to language barrier but you should clarify how long does your transaction pending and what is the exact reply of the support on your case.
Their accusations are not very complete and it is not clear what they are accusing without evidence, so if the withdrawal process is not instant then it is better to wait because sometimes there are delays, but the problem is OP said he didn't make a mistake and or wasn't locked? This confused me.
I experienced long withdrawal waiting on Duelbits using Dogecoin before that took me 4hrs to process. I contacted live support then the withdrawal process immediately. Sometime their automatic withdrawal system commit some error that cause delay.
OP is also not clear how long support did not answer his question?
Actually, what have you experienced with delayed withdrawals, the OP must be reasonable if there is any delay.
We don't know the actual case whether the withdrawal is still processing or he made a mistake in the bet?
