I am so cross - paid for parking on the RingGo app when taking my daughter to hospital - for some reason the car numberplate already on the app had a zero 0 instead of an O so I got a PCN. Appealed it with proof of a receipt from RingGo showing I was covered for the time in question but it was rejected. They don’t deny I paid they just say I inputted the car numberplate wrong and it’s the responsibility of the driver to get this right. I’m really not sure what to do - whether to pay up at the 50% discounted rate or appeal further and risk being liable for the full amount. I really don’t see how they can take the car-parking payment and issue a fine? WWYD?
