Telkom service sends me to fibre

I have been a Telkom customer for more than 20 years. My telephone line is out of order for the second time in two months. I logged a fault and have had no feedback in almost 4 weeks. Telkom is most definitely sending me to another service providers fibre service for my ADSL - I don't need your telephone line, Telkom, really only for my internet, but since I am paying to make telephone calls, please attend to my faulty line. Also, please refund me in FULL - the entire bill - for the past month as you have forced me to make expensive LOCAL landline calls on my cellphone when I am supposed to be able to do so on my landline - much cheaper. I repeat, please credit my ENTIRE bill. Please reinstate my landline.
