In the event any retailer or wholesale merchant is delinquent in the payment of the tax herein provided for, the Secretary may give notice of the amount of such delinquency by registered mail to all persons having in their possession or under their control any credits or other personal property belonging to such retailer or wholesale merchant or owing any debts to such taxpayer at the time of the receipt by them of such notice and thereafter any person so notified shall neither transfer nor make any other disposition of such credits, other personal property or debts until the Secretary shall have consented to a transfer or disposition or until 30 days shall have elapsed from and after the receipt of such notice. All persons so notified must within five days after receipt of such notice advise the Secretary of any and all such credits, other personal property or debts in their possession, under their control or owing by them as the case may be.
