I visited Mexico and my bill for the restaurant was $180 after gratuity. This was a written receipt and I paid with my credit card. I did not get a copy of the receipt or sign for anything. I was charged $250 instead and noticed only now a few days later. Am I able to dispute this with my credit card company or is it useless since I have no receipt? I will accept the loss if I have to, I should have taken a photo of the receipt, but would like to see if there's any options for me or not. Thanks!
