Vodacom Can't Complete A SIM swap

I am having extreme difficulty with completing a simple SIM swap for my number 082****023.

Last week Thursday I went in to Vodacom to complete a SIM swap as I needed a Nano SIM (bought a new phone which does not take the Micro SIM). The agent who assisted me completed the SIM swap and advised me to switch my phone off for approximately 3 hours and the SIM should be working thereafter. I followed these instructions and the SIM worked perfectly fine until the next day (Friday 6 Dec). The SIM then showed Emergency Calls Only, and I was unable to make/receive calls, SMS, etc.

I then went back to the same store on Tuesday 10 Dec and was told the SIM I had received was faulty, and Vodacom replaced it with a new SIM card. This did not solve the issue, I was told SIM swaps done after 6pm will only be completed 6am the following morning - my SIM showed the Emergency Calls Only message the following day.

I then went into the store AGAIN on Thursday 12 Dec and was told that I would need to switch my phone phone off for another 45 minutes, I was provided with a team leader's email address however as I am writing this review, I still do not have a SIM card which actually works.

I have now been to the Canal Walk Vodacom store THREE times in the last 7 days, and each time the representative I've spoken to has given me absolutely useless advice - I've been told it's due to load shedding, faulty SIM card, I've been told I need to wait and be patient while the issue is resolved.

I want to continue being a Vodacom customer as I have had this number for the last 7-8 years however your horrible customer service is making it extremely difficult for me to continue wanting to be a customer with you.

And the fact that nobody at Vodacom seems to know exactly what is going on or how to resolve the issue really paints a poor picture of the level of technical training your representatives receive.
