Do not have a clue about customer service!!!

I went to the Mtn Bela Bela shop 15/12/2015 for assistance regarding my Iphone 6 that was repaired and the consultant by the name of Veronica said that she would come back to me. On 17/12/2015 I went back to shop as I have heard nothing and spoke to Mieke - shop manager. She was very rude not professional at all she said that the lady did try to get hold of insurance but couldn't get any feedback and she didn't phone me - I explained the problem to her she told me that I made the mistake by paying the excess amount directly to MTN as requested by insurance dept and that she can't assist me anymore because it is me who made the mistake by paying the money to MTN - I told her and showed her the papers of MTN insurance that they requested the payment and then she said again it is now my problem to sort out as I have paid the money to MTN directly. When I told her that I'm the client and she must help me she looked at me and didn't say anything. I then told her that I would put in a complaint at MTN regarding her service and she rep**** WITH PLEASURE. I think this is pathetic and can't think that MTN employ staff like this!!!
