MTN South Africa - Shocking Service

I paid for a SIM swap for my sister because she has not been able to make or receive phone calls (incoming or outgoing). MTN has been completely unhelpful, both at branches and via phone - every person we speak to gives a different answer, and nothing gets resolved.

I completed the SIM swap at the MTN Cavendish branch in Cape Town on 20 January at 09:19. I was told it was a simple fix and that the problem would be sorted immediately. It was not. She still cannot make or receive calls.

She is on my contract and I pay it every month, on time. This has been dragging on far too long and the lack of ownership from MTN staff has been shocking.

I previously had LTE Business with MTN and cancelled due to the same issue - poor support and no accountability. Unfortunately, nothing has changed.

I am requesting urgent assistance to: 1. Restore full calling functionality immediately, and 2. Provide a clear explanation of what the issue is and why it has taken this long to resolve.

MTN needs to be better - this level of service is unacceptable.
