I had this notice from Excel today for allegedly overstaying for 16 mins in June on a three hours free car park.
I cannot find details of their appeals procedure on their website.
I have been reading a number of of posts and it seems that writing reasonably to the company is no good, some people advise ignoring the letters, some say to write that the driver should be approached by the company, not the keeper. Some of these posts are quite old, so legally the situation may have changed.
I would be grateful for any advice as to what is best to do now, I simply do not have the 60 pounds (going up to 100 if not paid within 14 days), they demand.
