A Scottish couple were flabbergasted after their energy bill changed from being in credit to £13,000 in debt overnight.
Stewart Neely is used to paying around £156 per month for gas and electricity to supplier OVO Energy via direct debit but found his account had gone from £189.99 in credit last Monday to £13,037.71 in arrears the next day.
The 54-year-old also claims previous meter readings and bills were altered to reflect the higher bill.
