Poor service

I went to do a Sim swap on Sunday at thavhani mall. Since you can not do it through the phone like other service providers. When I got home everything was fine the Sim card was working. But when I got to my lace of work later that night things changed. I thought it's because I don't have good coverage, but when roaming I do receive and make calls. Then I realized it's not because of the coverage something is not right. Today I decided to call Telekom with another network since I can not use my Telekom Sim card. And the lady who helped me indicated that the problem is with the Sim card, since I can not get the telkomsa or sign of the Sim card. And she said that I must go back to the store to get the Sim card sorted. I have traveled 200km to go do a Sim swap. And now the Sim card is not working. I have to travel another 200km to do the things that was not done right, at whose expense. Telekom please get your people trained, this kind of service is not on. The whole week I won't be receiving calls.
