Poor repair service

It's 09/06/2015 and I am without my phone. I physically went to the shop in Pretoria central to check for my device and i was told is being delivered to Hatfield. I called Vodacom to get a tracking number and when I called RAM the could not track my device with the number they gave me(VDC***). I called Vodacom again with this information and I did not get joy. I talked to the lady by the name Miyelani Sethole and through our conversation on the phone said they could not find any problem on my phone that makes me wonder because my phone was accessed by vodacom and then sent to Advance repair as they say and I am starting to wonder if it's true it did go there with this runaround I am getting. I did get a call from vodacom telling me they are going to repair the handet and i was happy and converted the complain to a compliment and now I am getting these news. I wonder if I should send an email to Thami Mazibuko Executive Head: Solutions management at Vodacom, so that he can see how we get treated by Vodacom. I am very upset and disappointed.
