Furious customer

My contract with Telkom for Smart Home Advanced expired a couple of weeks ago. I want a new contract for Unlimited Home for R599 p.m. I app**** online and after many weeks got an email stating " Unfortunately your application has been declined during our initial pre-vetting stage" I am a Telkom customer since 1978 and have never defaulted any payments. How dare they !!!!! Today I have phoned 10213 and after waiting for ages I was told that I must apply at a Telkom store, as the system does not allow me to take out a new/different contract. What an insufficient system !!!! I live in a wheelchair and it is very difficult for me to get to a store. On their website they state : Step 3: Place your order. You can do this in one of three ways, the Website, a Telkom store or the Call Centre on 10213 Seriously thinking of changing my Provider, as I am pretty annoyed
