UA Insider: My issue is that I made a R/T reservation on Sunday night (3/4). On Monday (3/5), I tried to change the return leg to a day later, but .bomb would not let me do it, it said I had to call it in. I tried calling but could not get through. So I tried cancelling the reservation on .bomb but again I got a message I had to call it in. I have been trying for the last 2 days to get through. I just don't have the time to hold for hours at a time to see if I get through. My issue is that since I did not make the change or cancellation within 24 hours, will I still have pay a change or cancellation fee. I can live with the reservation that I have now, but I think it is unacceptable I could not get through to someone to make a change or cancellation in a reasonable time.
