"Car park"

24/4/2015 Visited today with disabled Mother In Law [ Oncology Dept. ] for an appointment at 12.15. Waited and waited to leave at 2.00. we'd parked on the car park next to that Dept. and went to pay. Checked time and tariff = £3.75. Inserted ticket which wasn't identified by the machine. Tried again and again and finally pressed intercom. Abruptly told you'll have to come to the cabin. Which cabin. On the other car park. Which car park? The other one ! Can't you just open the barrier? No you'll have to come here! Waked to cabin to be told that the fee is £4.75. Asked why not £3.75 to be told that the time had just clicked over. Politely explained that if the machine had recognised the ticket and I'd not had to walk down to the other cabin the fee would have been £3.75. The member of staff told me that's not my problem the machine tells me how much to charge when I put the times in. Customer Care? It's not the money but the principle of how it was my fault and how ride and unhelpful the attendant was.
