SHELL EURO CAR PARK

I live in a Flat and don't have the means to wash my car. I'm a 65 year old women that had just recovered from Covid. The car had sat under the trees in our car park and it was a very hot week.
I knew I had to go shopping to Eastbourne so decided to jet was the car at The Boship Service Station at Hailsham. Before leaving home I made sure I had plenty of £1.00 coins to feed the machine.
Had to wait a little while for a free jet wash was available. So I sprayed the car off and the wheels, then shampooed it of with the help of a car sponge and then had to rinse it twice, giving the machine £8.00 in coins. I could now say the car was safe and the visibility clear enough to be safe to drive any distance, so went shopping.
A few weeks later I received a parking ticket for £100.00 saying I had been parked!
Well I of course appealed the charge and low and behold this was rejected and have just had to pay £60.00. I also sent a message to shell and received no acknowledgement, you all know how much these oil companies are making
I APPEAL TO ANYONE GOING TO THIS GARAGE DON'T , IT COULD HAPPEN TO YOU
