Poor customer service

Hello Peter, I went to Telkom to do a sim swap on the 01 May 2018. and I was assisted by a young lady called Paballo. I was told they had system error issues whereby I was told to take the simcard with and she will sort out the issues with her head office and revert back to me which never happened. I then called on the 8/5/2018 where I spoke to Thumeka who indicated that they take calls on behalf of the store and she will escalate it to the Store Manager but nothing happened. I made another call on the 14/05/2018 and Zandile gave me the same story as Thumeka and she will escalate to the shop. On the same date, 14/05 I then received a call form the so called Store Manager George Mfeka who promised to have received my query and he will look into it and revert back to me. I am still waiting for that to happen and to date 19 June 2018, I still don't have a working sim card. How does Telkom explain this mediocrity kind of service, whereby with other service providers you get a sim card and swap it on the same day within hours its working but it takes Telkom 2months for a non functioning sim swap and they still don't have the decency to tell me what's the held up.
