TELKOM wireless landline - FAILED TO REGISTER SIM

My 86 year old mother received a wireless phone from TELKOM on 12 October 2018. As yet, and today is 14th November, they have failed to register the SIM card associated with this phone. I have phoned repeatedly for the past 2 weeks and have spoken to various call centre assistants who assured me that the problem would be resolved the next day. I have provided each of them with her name, ID, address and ICCID no. Still nothing! It doesn't seem as though Telkom is interested but I am pretty sure they are going to expect payment for the month, even though she is not able to use this phone. Absolutely pathetic service!!
