A mum was left in a panic when energy company EDF charged her a whopping £336,865 for just one month of electricity.
Emma Martin, 40, was checking her account when she noticed that while her monthly gas payment was the same, her electric bill was extortionate.
Worried about the eye-watering cost, the dinner lady reached out to EDF to sort out the charge, but was unable to get an answer.
According to Wales Online, when she eventually got through to someone on the energy giant's online forum, she was left in further shock when simply asked "would you like to split the payment over 36 months?".
Emma, from Hartlepool, Durham, said: "When I first saw that number I had a bit of a panic because it's not what you expect to see when checking your monthly bills.
"I instantly knew there had been a mistake but no one from EDF would reassure me the problem would be sorted out.
"When I called their phone lines they just cut out and on their online chat they replied around once every 16 hours.
"When I finally did get through to someone they plainly asked me if I wanted to split the payment over 36 months which was just mental.
"As you can imagine I was very concerned."
EDF said a mistake had been made.
A spokesperson for EDF said: "When setting up the Direct Debit online, an incorrect electricity meter reading was submitted which resulted in the higher monthly charge.
"Mrs Martin has never received a bill for this amount and we’ve now corrected the meter readings."
