Poor after sales service

I purchased a wheelchair from Dischem a few years ago and found it to be of good quality and quite compact making it easy to transport. Recently one of the forks supporting one of the front wheels broke and I tried to order a pair of them from Thokomala and they only stock the wheel not the fork holding it. Their excuse is that the company that supp**** them closed down so I am I now supposed to s**** a wheelchair that cost close to R R 4500.00
