I've recently missed out on a refund of a flight I'd had to cancel because I'd misunderstood the instructions so didn't follow them properly. I was still in a state of shock when I cancelled it as I'd already checked in and packed and going over and over my travel arrangements for the next morning when a cardiologist phoned and told me not to travel. I was so shocked thinking about the ramifications on my holiday and my health that I failed to grasp a lot of what the reasons for them saying that and why i need new medications etc so I've had to write a letter asking. Is there a way of dealing with situations like this? I've thought afterwards that maybe I should have asked the airline and the doctor to explain everything in writing to me as I was autistic but I'm not sure if they'd have done that.
