Back in April, Tom Hoffman got a $66,000 water bill from the city of Dallas, Texas. Because he has autopay and the bill was for more than he had in his account, his bank locked down all his accounts, including his ATM and credit cards. He eventually got the problem straightened out and got an apology from the city. He also canceled his autopay. That was a smart move. The city recently sent him a bill for $67,000.
