Where is my upgrade phone!!!

I have reported my complaint on Hello Peter about a week ago, No response back from MTN.<br> I am very dissapointed in the most well known service provider. It's been almost a month and my upgrade phone has still not reach me, Im also dissapointed to know that I leave messages for Nicole Va Wyk to call me back, to provide feedback and no response. This morning I called again my phone has not yet been invoiced! How annoying!! Im being charged already and not even getting the benefit of the use yet! This is not fair, MTN should not be be charging me a cent for their lack on communication! I even changed my package due to no stock and was told bny Nicole she will make sure by phone reaches me by Tuesday 28/7, I expect her to make a special delivery today!!!!!
