Better I make a new account and ask them with a different username.
Create it from another account, with another email and other data cards (to avoid having the same IP address), but why not ask your friend or a trusted person to verify the account for you?
But are there any tricks to let you withdraw your funds without verifying yourself?
usually they will decline this but If you ask them to terminate your account after and send the funds back to the btc address where they were sent from?
It will not happen. There is nothing known as refunding payments to your old bitcoin/crypto address, but I do not know why you cannot withdraw. As far as I know, if you do not complete KYCs, you will no longer be able to trade or create offers and not withdraw. Are you sure of the withdrawal restrictions?
