Incompetency

I contacted Qatar Airways and spoke to Katleho Radebe on the 20th of June, to request information as to what would be needed to travel as I am living with oxygen. She advised me that they will require the medical report, of which I have provided related information as requested. If I don't initiate communication, no response is received to my queries. I have got all the calls and emails of our communication, whereby she advised that she will need to submit my document to head office a month before. I'm supposed to be departing on the 25th and I still don't have any approval that I can travel and whenever I call they say she is busy and I called at one point where I heard her saying in the background that she had already left and insisted I would hold for her to attend to my call. Yesterday I communicated with her and was asked to complete a form, which I have done. This morning I sent an email to follow up, now I have received a different form from herself and another individual and I don't know what is happening. I am extremely unhappy with this service as I have initiated the process in June and I am not happy with Katlego's service and I need the matter resolved today.
