Disappointed

<p>I made an overpayment on 25 November 2016. I called MTN a few minutes after realising that i paid too much. I requested a refund. Today is the 12th of December and still no feedback or refund from them. I was initially told that it would take 5 working days for the refund to go through. Now more than 2 weeks later still no refund. I have to call MTN call centre every day to follow up and still get no assitance even though the agents that I speak to promise to assist me and that this will be sorted out. i ask for the accounts department's direct number but they do not have one. what type of service is this. i am a very loyal custome but am disgusted by the lack of assistance.</p> <p> </p>
