Faulty electric wheelchair

I ordered an electronic wheelchair last year in December and in January,less than a month of using it, the bolt on the front wheel came off, I bought a new one and replaced it. Then in the same month, while I was in the wheelchair outside the same front wheel completely broke off and I fell with the wheelchair causing my arm to break. I tried logging a return online and emailing them with no success. I then called them and they said they will escalate the matter. This is very frustrating because not only did I sustain a broken bone and I am now in a cast but they are delaying making the collection. The wheelchair broke in January and it’s March now and I have not received any help. I can’t even go anywhere because my wheelchair is broken and Makro is not resolving the problem. I paid a lot of money for that electric wheelchair and I was expecting a quality wheelchair with a strong frame but that is not what I received. Even the government wheelchair has a stronger frame than this expensive one. I am very disappointed by Makro and I don’t recommend their electric wheelchairs
