They booked an airline ticket to Mexico for my friend for 1 day instead of 10 because of a keying error and when he discovered it they said he would be responsible for paying the ticket change fee because he approved it on the paper which they casually had him sign. A professional and competent agent would take the time to enter the dates correctly and then verbally confirm with the customer that those are the dates they are wishing. Neither of those things happened and when it came to taking professional responsibility they chose to say he should have discovered the error and corrected them. These are some of the worst business practices.
