Yahaya Wahab in Kuala Lampur, Malaysia, had disconnected his deceased father's phone line in January 2006, so you can imagine his surprise months later that his phone company still sent him a bill. He was more surprised to see the bill: 806,400,000,000,000.01 ringgit (the equivalent of 218 TRILLION US dollars) to be paid in the next 10 days. For comparison, the US National Debt is just over $13.8 trillion.
Yahaya's father had left behind an outstanding 84 ringgit ($23) bill, which Wahab said he took care of before the disconnection. The multi-trillion dollar bill from Telekom Malaysia was probably a mistake, and Yahaya said he would fight it if it he ever had to go to court for it.
