Tonight I came home to a letter from the city with the words "Final Notice" on it and dire warnings of damage to my credit if I didn't pay up immediately. In fact, it suggested I might already have been dinged. I had no idea what they were talking about. I pay all my bills promptly. Fortunately, the city has representatives answering the phone unti 6:30PM. Thank God for good customer service!
It turns out that they thought my house was still a rental and they thought I owed them rental taxes. Not only that, they had been mailing the bills to my address from years ago. The pigs that live there now never told the city I didn't live there and never returned the mail. How they managed to finally send the notice to the right address is beyond me.
A form filled out and a follow-up phone call and this should all be cleared up. I thought I was going to have a heart attack when I opened that letter.
