90 days later no response on lost airtime

Almost 100 days ago I called the MTN call centre to lodge a complaint about lost airtime ( approximately R440), and spoke to 10 agents who sent me from pillar to post, quite rudely might I add. I finally spoke to an agent by the name of Sonwabo and requested that he requests the tapes of my earlier conversation where I was advised that I wont lose the airtime. on 16 Nov he promised to do so and revert within 4 days but has been quite. I have twitted MTNZA and MTNSERVICE which promised to come back to me but nothing. I have written on hello peter but again nothing with the exception of a response saying they will respond (Nompumelelo REQ: ***). <br> <br> Even after this message from MTN<br> <br> Rest assured, it is not our intention to displease you. We look forward to improving on the service delivery to you. Regards, Ayanda REQ: ***<br> <br>
