Use the address letter for letter

Ask for certified mail
Ask at the counter for the certified service with a return receipt: the fee is on top of the postage, the receipt is postmarked, and the article number traces the delivery.
Keep what the post office gives you
Keep your copy of the letter, the receipt and the delivery record in one place. The delivery date is the one to quote if the account is billed again.
The letter, written out
