In January 2000, a man received a bill for his, as yet unused credit card, stating that he owed $0.00. He ignored it and threw it away. In February, he received another and threw that one away, too. The following month the credit card company sent him a very nasty note stating that they were going to cancel his card if he didn't send them $0.00.
He called them and was told that it was a computer error, and that they would take care of it.
The following month he decided that it was about time that he tried 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 when he produced his credit card in payment for his purchases, he found that his card had been cancelled.
He called the credit card company who apologized for the computer error once again, and was told that they would take care of it. The next day he got a bill for $0.00 stating that payment was now overdue. Assuming that having spoken to the credit card company only the previous day, 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 got 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 beat the company at their own game by mailing 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 what he was doing 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 now 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, and unless he sent a check 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.
