I have written a formal report of complaint since July 2017 but even today it has not yet been attended even though they send email promising that they will attend to it within a certain period of time but that has never happened. Below is a reference number: MTN Complaints Report: June/July 2017 [# ********** 4] Inbox

The emails had been sent for numerous occasions TO: 1. Complaints ********** 2. ********** ********** 3. Customercare **********

I even raised by unhappiness with their service but even now nothing has happened, my details are as follows:
