Telkom pre-paid landline - no delivery

Can I give a - star rating? My mom-in-law's phone was cut in December 2018. After numerous calls etc. we got a ref number on the 16/01/2019 according to the person they do not fix lines any more and she will get a landline lookalike and it will be delivered in 4 weeks. We kept on checking and it was 3 weeks, 2 weeks... then nothing only to find out that the order was canceled!!! We placed other order this month 24 May and been promised that she will have a phone by the end of May. Only to find out today on the 29th that there is no order. The whole time we had been shunt around between the 10213 number and ********** 263 number telling us it is the other departments problem and not them. I asked for managers to phone me in this week - still nothing. I really do not know what to do any more. My mom-in-law is nearly 90 years old and need a phone to contact her family overseas.
