Bought petrol at my local Shell station on the 18th paid for and showing on my bank statement for £40.03. Only to get a letter from forecourteye for petrol on the 19th for £37.65 which is not true. Have written and they have not provided proof of me pumping petrol on the 19th, they sent an auto generated letter, saying its witnesses from the garage. I am ready to go to court with this. Any advise on what to do, never been in this situation. We are in our 60s and would never do such. HELP anyone
