I want to ask for help so that if they can cancel my flight and return the money or move my flight for another date I will explain the reason.*** weeks ago my father-in-law passed away. We hired a funeral service where the reason is to take him to give his Christian sepulture to Guatemala. the agent of the funeral home had given us a date where he would buy the flight to send the body of my fire and it would be the day ** to October ** but * hours ago the agent of the funeral home informed me that he had not found a flight and that I knew if it would be possible to send the body in these days. leaving us in a bad position because also for work we do not have many days of leave and also my flight was for a date and the main thing for me is to be with my husband and be in the last residence of my father-in-law.**I ask you to really understand me we are so disappointed of the funeral home by the time*delayed and being unresponsive with us since we now do not find ourselves in this situation because we would lose our presence the moment the body arrives in Guatemala and without anyone receiving it, since his wife and children all moved from Houston to Guatemala at that time.*for the same reason I take the boldness of losing them the help that cancel my flight and that they give me back my money since as you can verify the agent of the funeral home does not have a date agreed to send the please can you contact to me in this email o in my email. but please really I need you help. if you need all information I have the death paper and letter for the funeral . is if you need because I don't have here the option for attachemen the letter
