<prompt> Human: I went to a local pub owned by a high end hotel last week for a college football game with friends. The bill came to 47.88. It was incredibly poor service where he forgot to bring me a glass for a pitcher of beer on the table, never came back to take our food order so we ordered from another waitress, and didnt check on us until he dropped off our checks. Due to this, I wrote 50.00 in the total line and signed the merchant copy. I made the mistake of not keeping my receipt and looked at my bank statement a few days later and it showed 60.00 was debited from my account. I called the general manager who sent me the receipt that they had on file over and it shows a total of 47.88 with a 12.12 cent tip not in my hand writing as well as what is trying to be my signature that is clearly not mine. The general manager told me I need to file a formal complaint with the hotels accounting department and there was nothing he could do other than talk with the employee. What options do I have in this situation?  <response>: Call your credit card company and file a chargeback.
