All persons so notified shall forthwith after receipt of the notice advise the department of all credits, other personal property, or debts in their possession, under their control, or owing by them. If the notice seeks to prevent the transfer or other disposition of a deposit in a bank or other credits or personal property in the possession or under the control of a bank, the notice to be effective shall state the amount, interest, and penalty due from the person and shall be delivered or mailed to the branch or office of the bank at which the deposit is carried or at which the credits or personal property is held. Notwithstanding any other provision, with respect to a deposit in a bank or other credits or personal property in the possession or under the control of a bank, the notice shall only be effective with respect to an amount not in excess of two times the amount, interest, and penalty due from the person.
