If your bank won't allow you to make withdrawals from your account, you should ask for an explanation. One reason for the bank to prevent withdrawals might be as simple as the account type. If the account is a time deposit, withdrawals may be prohibited until the maturity date or without advance notice, depending on the deposit contract. It's also possible that your account has been levied by a state tax bureau, and all sums deposited to the account for a period of time will be subject to the levy, which means every dollar deposited gets turned over to the tax bureau.
Is it possible that your account is overdrawn, either because you've withdrawn funds in excess of what you have deposited or because a check you deposited was returned unpaid? If you do have an overdraft, the bank legitimately will accept only deposits until the overdraft is cleared, and may in fact, require that the account be closed.
Those are some of the reasons that might explain why you can't withdraw from the account. For the actual reason in your case, you'll have to inquire of the bank.
