We parked in Adams St car park in Cardiff. We paid at the machine. We got the ticket. Thought nothing of until about a month later we got a fine to say we had not paid. We had thrown the ticket away as thought no need of it now. As we paid by credit card we sent copies of the statement stating it was for Adams St car park. They sent an email saying we had won our appeal. But the cheeky people said that we should make sure we pay in future!
