Wireless phone

It has been a year now that my mother changed over to the wireless phone and she has been unable to use the phone since she received it, despite having paid for the service and numerous visits to the Telkom store and countless phone calls to 10210 regarding this matter. Everytime I called in I had to give the sim card number and was told we just have to wait it will be activated. I have spoken to a manager regarding this as well at the call centre and she said she would "personally look into the matter and see that it's done and keep me I formed". That was almost 2 months ago and I have not heard from her again. I asked for a mother manager to speak to on Friday and was told that he would call me back as "he is busy with another client". I am still waiting for the call. My mother is 74 yo and already had 2 strokes. She needs to have access to a working phone in the event something happens to her and she has a problem with her cellphone. Telkom does not care about their clients and just continue with the pathetic service and expect us the consumer to be happy with it. My mother sis everything she was supposed to to move over to the wireless phone but yet she cant use it. Yesterday she received a message to say that the wireless service has to be renewed as it's a year already. Renew what? Something she hasn't been able to use for a year and have paid for?? How come the system shows it's a year that she has wireless and it's not even active? We need a other service provider to replace Telkom!!! The level of service is unacceptable
