Poor customer service from repairs department

Good morning, I just had a very bad encounter with one of your service consultant in your repairs department. Unfortunately I never got her name. I had called to enquirer about an AG Chrome Tablet 7-inch that had been collected from my office on the 13th of April 2016 by a courier company on behalf of Cell C. I told her from the onset that I don't have the receipt with the tracking number and wanted to know the whereabouts of my tablet because primary phone had stopped working and I'm in need of a phone. She then told me that the phone was never received by Cell C and that she is unable to assist. Now, I take full ownership of the fact that I didn't have my tracking number but what I didn't appreciate was her unwillingness to help and attitude. In the end I was the one who called the courier service to try and get the tracking number. I don't mind doing this, but I'm a paying customer who hasn't had a phone in over 2 week but have been paying, the little that i would like is a bit of assistance and less attitude. Plus, one just can't be told that their phone is nowhere to be found without even being advised on what alternative ways are available to try and track the whereabouts of the phone. That is not my idea of good business relations and I'm very dissapointed in the manner in which this was handled.
