I called to make a change to call center, after 3 hrs they were able to do it, but said they were having problems with System. Next day tried to check for reservation and It gave and error or cancel, Its been 3 days and been unable to get this solve, I tried messenger, chat, email, and the call center takes about 2 hours if ur lucky to get on the phone line, they keep transferring from one to the other, and no one solves anything!
