MTN cancellation headache

I am extremely disappointed with the service I have received from MTN regarding the cancellation of my month-to-month WiFi contract.

I took out the contract in November 2025. After realizing that the router did not work properly in my area, I returned the router and requested cancellation of the contract on 13 January 2026.

Despite returning the router to MTN, I have continued receiving statements and being billed for a service I no longer use. I have visited the MTN store at Southgate Mall several times trying to resolve this matter. Each time I am told that the contract has been cancelled, but then another statement arrives showing an outstanding balance.

On one occasion, I was told the cancellation could not proceed because I allegedly owed R11.40, which I paid immediately in store. Before that, I was informed that I owed R630, which I also paid because I simply wanted this matter resolved. However, at the end of April I received yet another statement saying I now owe R339.

To make matters worse, MTN has listed me with the credit bureaus for missed payments on a contract that I have repeatedly attempted to cancel since January.

I have also contacted 135 as advised by the store, only for the call centre to refer me back to the store again. I feel like I am being sent from pillar to post with no real assistance.

I have done everything requested of me, returned the router, visited the store multiple times, made payments when requested, and followed all instructions given. Yet the contract still remains active and I continue to be billed unfairly.

I have genuinely run out of options and would appreciate urgent intervention from MTN to:

1. Cancel this contract immediately; 2. Reverse all unfair charges after 13 January 2026; and 3. Remove the negative credit bureau listing caused by this matter.
