Purposely block my account from internal transfer

This is really a tricky way, please read this carefully.Im running in profit every week and not running illegally.Not much entry per day .Less than 10 entry per day.1st time withdrawal,they hold for 3 days and release the money.3rd time not able to withdraw.This is where the tricky part comes.In order to withdraw,I need to transfer the money from trading ACC into wallet.They purposely disabled the internal transfer.No email or notification received.I asked them why do this and they ask for selfie photo with utility bill.After provide it,no response and the next day they ask for video.From.here,I can see that they are trying to delay the withdrawal and not responding to my email.Note that they never mentioned anything why they block the internal transfer to me.This is kind of abusive and this kind of broker should be reported.
