I wonder if the mega rich occasionally get erroneous charges like this and just don't notice. The sort of people that keep a few hundred k in their current account as working capital in case they want to buy a painting on the way home from work.
Eon forgot to charge me for any gas (on what was supposed to be a combined leccy and gas tariff) for 6 years. When they noticed they asked me to pay for the last 6 months' worth and after a little harumphing from me we settled on 3 months.
