Service/ Repair Centre

I am so disappointed with the service that I am receiving or rather NOT RECEIVING from Hisense South Africa I bought a Pure 1mobile phone in October 2014, the screen broke on 6 February 2015 (which I am willing to pay for). Seems no one knows where I can get my mobile phone fixed in Johannesburg. I have been waiting for a quotation from the service centre since 12 February 2015. <br> I am yet to receive a response - regardless of the 4 follow-ups done to date.
