I had to cancel an itinerary for Mexico through FB with AeroMexico due to an anticipated Covid lock-down at the final destination. I had booked ONE multi city round trip, and gave PLENTY of notice of the cancellation. But I was told that I could only use the credit of ONE flight - segment of that trip against the re-booked itinerary. I protested, as it was not me that booked separate "legs" - and after about TWO WEEKS the contact assured me that they had cleared a full credit against the new itinerary with AM… Another week later and much "badgering" by me to get FB to book me, I'm now told it cannot be done as AM now wont allow it. So you drag me out the best part of a month and then to let me down. Totally, totally disgraceful and unacceptable. I am going to make sure that EVERYONE on the web, friends as well understand what a useless shower of clowns operates FB. You have had a lot of travel from me over the past two years, but HELL will freeze over before I even look at your site again! Disgusted.
