Today's award goes to a French telephone company, not only for its initial billing mistake, but for its response when queried. The BBC reports:
A woman in south-west France, who received a telephone bill of nearly 12 quadrillion euros, has had the real amount she owed waived - after the company admitted its mistake.
Solenne San Jose, from Pessac outside Bordeaux, said she received a huge shock when she opened the bill for 11,721,000,000,000,000 euros [about US $15,192,760,200,000,000 at current exchange rates].
This is nearly 6,000 times France's annual economic output.
. . .
The phone company, Bouygues Telecom, initially told her there was nothing they could do to amend the computer-generated statement and later offered to set up instalments to pay off the bill.
In the end, the company admitted the bill should have been for 117.21 euros only, and eventually waived it altogether.

What do they mean, "nothing they could do"? The entire world's annual GDP is only about $65 trillion! It'd take the total combined economic output of every nation on earth for well over two centuries to pay that bill! Just what sort of "instalments" did they have in mind?
