Month-to-month contract cancellation hussle

I have had contracts with other network service providers and I have to say MTN has by far the worst customer service. I have been trying to cancel my month-to-month contract with them and have had 0 success till now. I was instructed to go inside their stores and went to MTN Maponya on the 29/03/2026. Just when I thought I was finally succeeding with the cancellation process after they took the router and captured all the details they required from me, I was provided a number to call and provide an “IRMS” number. I called your contact centre contract department on the 30/03/2026 at 13:14 and was informed that they cannot find any cancellation that has been loaded on their system and I need to go back to Maponya Mall to get assisted! I called MTN Maponya numerous times from 13:24 yesterday and eventually spoke to Rethabile. She requested for my details including the IRMs number they had issued me and promised me a call back with the feedback on my request. She called me back at 15:52 only to tell me their system is “down” and would get back to me once it’s up and running. I am still waiting for communication from your people and nothing till now. You have taken your router! Please cancel the contract!
