Worst service ever - Please help

Good day<br> <br> My name is Elmien Murphy. I am due for an upgrade on my cellphone contract***). Saturday(20th February 2016) I phoned MTN and spoke to Thandeka Mdlovu at the JHB branch. As the new upgrade consists of a cellphone as well as a tv she needed a tv license and other documents. She asked that I send them via email to her and I did so on Monday(22nd February 2016). I have not received any reply from her stating that she did receive my documents and that the upgrade will be going through. When I log onto the MTN site it says that the upgrade is still pending. I phoned on Monday(at least 3 times) and every time I had to hear that she is busy and would phone back. On Tuesday and Wednesday the same thing happened. This morning I phoned again. First someone told me that she is on training today and later on I phoned again and then someone told me that she is on lunch. Now who is lying to who???<br> <br> I need answers TODAY as this is unacceptable. As I feel at this moment I am considering cancelling my contract as I am running out of patience. <br> <br> Elmien Murphy<br> <br>
