My mother and I were to fly out from Mexico City to Bs As Argentina on march 23, 2020 and on march 17th 2020 our flight was canceled due to Covid. for the last month we wrote to customer support to get a new ticket number since my mothers ticket was archive. I received a letter on February 18, 2021 from customer support that I can used the ticket, to call customer service to make my reservation. Right now I made 10 calls, spoke with 4 supervisor, was on hold for more than 10 hours, got cut off 3 times and still do not have a ticket for my mother. I was told by one of the supervisors that Monday I would have a ticket. My mother is 94 years old and needs to return to Argentina by march 1st 2021. I need help to resolve this asap
