In March 1992, a man living in Newton near Boston, Massachusetts, received a bill for his as-yet-unused credit card stating that he owed $0.00. He ignored it and threw it away. In April, he received another bill and threw that one away too. The following month, the credit card company sent him a very nasty note stating they were going to cancel his card if he didn’t send them $0.00 by return of post. He called them, talked to them, and they said it was a computer error and told him they’d take care of it.
The following month, he decided that it was about time to try out the troublesome credit card, figuring that if there were purchases on his account, it would put an end to his ridiculous predicament. However, in the first store where he produced his credit card for payment, he found that his card had been canceled. He called the credit card company, who apologized for the computer error once again and said they would take care of it.
The next day, he got a bill for $0.00, stating that payment was now overdue. Assuming that the latest bill was yet another mistake, he ignored it, trusting that the company would be as good as their word and sort the problem out. The next month, he received a bill for $0.00, stating that he had 10 days to pay his account or the company would have to take steps to recover the debt.
Finally giving in, he thought he would play the company at their own game and mailed them a check for $0.00. The computer duly processed his account and returned a statement to the effect that he now owed the credit card company nothing at all. A week later, the man’s bank called him, asking him why he was writing a check for $0.00. After a lengthy explanation, the bank replied that the $0.00 check had caused their check processing software to fail. The bank could not process any checks from any of their customers that day because the check for $0.00 was causing the computer to crash.
The following month, the man received a letter from the credit card company claiming that his check had bounced and that he now owed them $0.00. Unless he sent a check by return of post, they would be taking steps to recover the debt. The man, who had been considering buying his wife a computer for her birthday, bought her a typewriter instead.
