No consideration for people with health issues

The below rcomplaint was submitted on the 27th of March, to date no response. The wheelchair assistant didn't come to fetch me from the lounge, he confirmed that he would fetch me at 1pm. I asked the lounge assistant to call more than 5 times from 1pm and she kept saying they are on their way, I then received an SMS to say I need to be at the gate in 15 minutes otherwise I will miss the flight. I made my son run and I tried to catch up and just made it. the flight supervisor had a no care attitude, no sympathy and told me I should have waited, waited and what missed my flight? then he changed his story that I said I told the wheelchair assistant to not fetch me, now why would I do that when I know I can't walk for a long distance. The supervisor was so rude no sorry or any sympathy and he could see i was in tears in pain. when i got on the flight the attendant gave me water as she could see i was struggling and gave me the first seat available so i don't have to waal further down to my seat. I am now very sick back home and need compensation.
