John O'Connell is the Director of the Tax Payers Alliance.
He told Pirate FM issues like that should be sorted out straight away.
"Parking can be very expensive, and motorists are already paying quite a lot to park in town, it is important that charges are not used as a way to plug gaps in the finances, but a reasonable charge will help make sure that the high streets stay busy and that local shops can keep on operating.
"Motorists are already paying a lot for parking so to find out that they have been overcharged, they will be doubly angry. I think the council should act immediately to recompense the people who have overpaid and they should make sure their new apps are working before they put them live."
