Poor service with regards to my phone

I visited the rosebank Telkom store about a headset phone contract I have with them. The phone randomly stops working and this is the second time I have had to take it in for repairs. I was so mad when I got to the shop about their dysfunctional phone that I still pay for, only to be told by the teller that is just a phone and that I need to relax. That man was very rude and showed no emphathy. He kept talking to his colleagues and he was eating candy as if my matter is not of urgency. I have only had the since February 2015, it's September now and already I had to book the phone for repairs twice. I am not happy at sll rver since I ported to Telkom Mobile
