Horrific! 80 year old still waiting for her phone!

My 80 year old grandmother moved to Cape Town last month. Before she moved she got hold of Telkom to come and set up her new phone. They promised they would be there on the 16 March, the day after she moved in. However, a week before the move they called and cancelled saying they would come on the 26 March. This was a bit annoying as it meant she would go another week without a phone as she has no cellphone, as she is nearly blind and has very poor reception in Pinelands where she now stays. The 26 March came and went and no one rocked up, nor called. I have called the call centre but due to a strike it is closed. I then SMS'd the SMS line and 24 hours later no one has responded. My ref is 116 33 54 57. I live 500km away from my grandmother, she is all alone where she is and has absolutely no means of contacting anyone. This is obviously awful on its own, but what if an emergency occurred? I will be holding Telkom liable in such a case. I am appalled at the lack of service. Please can you get hold of me TODAY, this is unacceptable and I will not hesitate to take this further should I not receive a call today as this is now beyond belief.
