Congestion charge chiefs in London have apologised twice for wrongly sending a Powys man 65 bills.
Earlier this month, David Timothy, 47, from Brecon, received 31 penalty notices even though he had not been to London for 25 years.
But a day after receiving a written apology from Transport for London (TFL), which enforces the charge, he was sent another 34 bills.
TFL apologised again, blaming the second blunder on a "processing error".
Royal Mail worker Mr Timothy was originally sent bills adding up to £2,480, which would have risen to more than £4,000 had they remained unpaid.
He said he had only owned the car identified in the bills for a year, but the 31 congestion charge notices dated back to a five-month period in 2004.
