"Smart parking"

I feel the signs for the car parking at Aldershot centre for health need to be reviewed. After speaking to others regarding parking at the health centre I have now found I am not alone with the issue I am currently having. It clearly displays FREE 15 MINITE PARKING which I am now being requested to pay £160 to a debt collector due to appealing the original £60 ticket I received. As in a hurry to pick up a prescription I did not get out of the car to read the significantly smaller and less bold small print advising you should enter your registration for this. I feel this too should be in bold and the cost of the fine itself should be addressed as it is far out of proportion for the financial situation of most residents in this area. I stayed in the car park for 9 minutes and am now expected to pay £160. I understand the NHS property services feels it benefits the money pot for local NHS services and facilities. But I think it is extortionate and financially crippling for those it catches out with the unfair signage.
