3x Sim Swap with no Service

On Sunday 28 October 2018, I have called vodacom customer for sim swap which went through successfully. Then on Monday 29th I could make calls until 21:22. Unfortunately when I tried to use the SIM card the following day 30th. Message on phone was “No service”well since I was next to the mall. I went into Centurion Mall vodacom franchise(Alison Communications)consultant(6-Masm07) tried it with still on his phone he got the same message that’s when he suggested another sim swap. Unfortunately his I got the same message with his sim after the suggested 4 hrs. I called customer care again on Wednesday 31st and spoke to Ayanda who also suggested a sim swap and didn’t want to listen to me as a customer. I asked what difference will it bring because I have tried that and the problem is not the sim but the service? She was rude and said she would call back after 1pm to check and I am sure she couldn’t go through if she did call because still there was no service after the 3rd sim swap in Woodmead at Vodashop Retail Park assisted by consultant 5-Johannes who gave different SIM card and requested I sign a form of service. It also failed after 2hrs and when I called back he also ignored my calls by tell the person who answered the phone that he was not around.
