Bad service Telkom

About a month ago I went to the Kenilworth Centre branch in Cape Town because I had no network on the waya waya pre paid phone. The consultant said he can't see why it is ceased. He let me fill in forms and told me telkom will get back to me if about a month now and no telkom contact. Today the 9/10/2019 I went to Claremont telkom in Cape Town the consultant told me Telkom cut all the pre paid lines. His pre paid phone at home was also cut. Why did telkom deliver the new cordless phone with simcard if they knew they going to cut the prepaid lines. But why whywhy. I have a 76 year old father diabetic in a wheelchair that I need to contact during the day. He can't always hear his cellphone

What can I do
