C E are just here to rip people off

A young lady bought a wheelchair from them a few years back, a Quickie. Yesterday I took the rims in to have new tyres fitted. According to the manual that came with the. Chair, the rim size is 24". The young man that works at the Pretoria branch then informs me that they aren't that size but bigger. He cannot fit the 24" tyre as he hasn't the facility to stretch the tyre. I must go to another co to see if they can do it. That got my anger level rising , as how can you supply something so important and not be able to supply the tyres for said. They are just selling stuff that they cannot fix . Knowing that if you can't do a simple thing like supply tyres. The client is then forced to buy a new chair, that is not how you do business ,unless you are only in the business to tip disabled people off. I find this disgusting for a company that are in the industry to help
