A driver saw red after he tried to pay for to park for two hours but was charged for a week.
Tony Harper wanted to pay £2.50 to park at Pierside car park in Skegness, but it cost £36.
Tony, from Nottingham, was using the new pay by phone service at the car park run by East Lindsey District Council.
Registering with the cashless system he paid for an initial two hours parking without a glitch. However, when he tried to make a further payment he received the bumper bill.
The message on his mobile said Tony, 55, had extended his stay from July 28 to August 4 - a total of six days 22 hours.
He was furious he had to make several calls to the council and company that operates the system before the charge was cancelled.
Tony said: “I got a message on my phone that the parking was running out.
“There was only 20 minutes left before the charge period ended.
“It seems that if there is less than an hour before the parking charge expires the only payment it will take is for another seven days.”
“They have got this system in place that does not work. It left me feeling duped. I do not feel confident using it again”
A spokesman for East Lindsey District Council said: “We have discussed the issue directly with the motorist concerned and have been able to identify an issue which is now in the process of being resolved by the provider of the pay by phone service.
“We have refunded the payment and apologise for the inconvenience caused.
“Since the introduction of cashless parking in East Lindsey in April, motorists have purchased 2,938 parking periods taking advantage of the opportunity paying by phone presents.”
