Once your package is in their hand, they have the collateral to do any criminal activities upon you. They are one of the biggest Mafia criminal organizations in Mexico, bear an international shipping company's name. They also thought they partially control the local government, so they can do whatever they want. If you encounter any difficulties with FedEx, please report your local fiscalia office if they try to charge you extra money or they stole your package.
