Poor service

upgrade in march 2015 by june/july the **** phone was giving me problems and you people were on strike. In sept i took the phone in for a repair/ warr ass. It was rejected because of what they call drop dents which was false the rim on the phone had some scarfing from the pouch, at that stage i was ready to cancel the contract, but Martin manager/supervisor told me that they will repair phone at no charge to me. I got back the phone on the 11 oct it worked for all of a month and it doing the same thing again. I call the call centre spoke to a lady by the name of Akona whose team leader was to call me back up to this day i havent heard from him the was on the 8 nov on the 24 nov i called again they told me to go back to the store and they will sort it out at store level l. I went to your northgate branch and spoke to Martin who then said he'd call me with feedback i still javent heard from him. I try calling not having joy. Im not interested in have this phone repaired i either want a new phone or cancel the contract and aint paying no canellationl fee, thats for damn sure.
