No help for faulty product

I upgraded my device via the call centre. It was delivered to me via courier on 04 May 2015. On 06 May 2015 I reported to the call centre that the device was faulty I was advised that the courier company will be sent to collect the device so it can go for repairs. On 13 May 2015 I call again and reported the problem again because my device hadn't been collected. On 25 May I once again reported the problem to the call centre and again on 03 June I re-logged the call with the call centre. <br> I travelled 200km to the nearest branch in Pietermaritzburg and they refused to help me, they said that I must deal with head office it isn't their problem<br> It has now been 6 weeks since I first reported the problem and still I cant get help<br> This is really pathetic service, what is the use of having a call centre if they don't help you!!!
