Worst service Ever, 3 days trying to contact somebody to get information to travel to Mexico, anybody answers the phone, not counting that they don't answer emails either. And after all this time the mailboxes are full, so not even a chance to leave a message to see if somebody can answer a question.
Receptionist nice person but no knowledge whatsoever about visas, transit, etc.
