Last October, while in Mexico for a family wedding, a traveler noticed a suspicious $1,500 charge on their credit card made at a restaurant in Mexico City on the day they flew back to the US. Despite disputing the charge, their bank, Wells Fargo, repeatedly denied the claim. After intervention, the bank refunded the charge, acknowledging the need for better procedures. The incident highlights the importance of monitoring credit card transactions while traveling and the potential risks of using card readers at gas stations. The gas station operator and local authorities are investigating the matter. Travelers are advised to be cautious and consider alternative payment methods in the region.
