One of the greatest scam companies of the XXI century. If your deliveries have to go through these guys, make sure you check your products before letting the mailman go. They steal stuff, they lose stuff and their customer service is possibly one of the worst I've ever seen. I feel terrible for Brazil and Brazilians for depending so much on these folks.

Poor Custommer Experience with mail/package and site service (broken links, slow site) and the description of the time to delivery does not match reality.
