Shocking service

On the 12 aug 2015 my huewei y600 stopped working. I took it to jabulani store for assistance. I get there I am told it is a software problem and if it was a weekend they would do the software for me but they are booked and I must pay 900 for my screen to be fixed first before they can help me. My phone is only 8 months old and I'm already having hassles. I was given a number to call *** when I called Augustine Qekisi answered and she was rude speaking over me and hung up on me. I called again and spoke to Thelma Mo***eng she took my number and said her team leader will call me and no one came back to me.I can not phone or email but vodacom got their profit and I am sitting with the phone that does not work. Shockinly last year I brought my becauuse I blocked. My phone and they fixed my phone with th e softyware problem and I paid R300 and they were no problems
