Device not repaired

I took in my S4 device on 5th December 2014 as my camera no longer zoomed in and out and my chat on had also stopped working. I was told that this will be fixed and that a new software had to be installed. Once my device came back a few days later my camera stopped working. I then took it in again on 18 December 2014 and fetched my phone on 19 December 2014 at about 3pm and it was still not fixed as it was still in the queue. I then went back on 28 January 2015 and was told my front camera broke and they can't fix cause it's out of warranty. This is ridiculous as I am on a contract and my warranty only end in July. I then called head office and spoke to the following people which and no assistance was obtained from them. Namhla Mabena, Tshepo Makwela (coach) and Innocent Mauleverer (supervisor). I was promised to be called back to be updated on the progress of my matter but none of that has actually happened. I would like to Also make a comment about the boksburg customer care receptionist. This lady is rude and very arrogant I suggest that someone goes through her job spec with her so that she may understand what her job entails.
