I've recieved a letter from Horizon charging me £70 for over staying at a Tesco car park. And that would be fair enough if I had been there between 8.03 and 14.26 but I was actually there between 8.08 and 8.24 and then 13.59 and 14.26 according to Google maps. I went back because I had forgotten something and Tesco is my happy place.
If I pay it now, it will cost £35. Is it worth contesting?
