A man said he felt like he was being mugged when he received a £4,000 electricity bill from his energy provider.
Christopher Barnes, 58, said his last OVO bill was £59.82 and he paid it in full on October 11.
The disabled man, who lives in a one-bedroom flat in Jesmond, Newcastle, said he was "shocked" and "appalled" when he received another bill for the amount of £4,190.77 earlier this month.
