MTN SA Terrible customer support process

I'm experiencing an issue with MTN South Africa. My contract expired, and I wanted to upgrade, but the store couldn't update my passport details. They attempted to transfer my contract to my new passport, which resulted in my account being in limbo. Despite numerous calls and emails with MTN customer support,retentions department and store over the past month+, the issue remains unresolved. I'm now trying to cancel my contract, but that's taking over a week due to lack of assistance. I'm frustrated with the constant handovers between teams and the unprofessional service. I need help resolving this issue immediately. The agents keep passing the buck and throwing the issue over the hedge and i have to explain this case every single time. I was promised a call with a manager to help reolve this on 17/10/2025 but i still am waiting. I even followed up twice in one morning now and there still is no movement. This is torture surely.
