Paying for non existent contract device

I Upgraded by contract in July @ the Galleria Mall shop after quite a number of encouraging calls from cell c for me to upgrade, well angikho lapho. Got myself a nice Huawei Nova 8i , I was ecstatic needless to say that happiness what shot lived. Exactly two weeks later the device stopped working, the screen froze, i couldn't make or receive calls, it would shut down mid call, it wouldn't restart, etc. I wen to the shop ( indicated above) informed them of the issue and I was advised to book the device in for assessment which I was very much unhappy with, I mean the ink on the contract is not even dry yet! Well, since everyone was looking at me like am a madwoman I gave in and the device was booked in for repairs! . A month and half later I got the device back and went out of town only to find that the issue on the device was never resolved. sadly I couldn't drive back and I was going to be away for some time, so i kept the good for nothing phone with me all that time. On my return I sent it straight to the shop. The sales lady ( Tamara) whom I had purchased the phone from , booked the device in AGAIN for repairs. Its been weeks now the device is not back, there's no feedback, CellC customer service consultants keep telling me the device is still with the manufacture for "assessment" and they are 'escalating the matter ( which is just some term to bluff me since there hasn't been any response to that "escalation". Seriously what the hell is being assessed or repaired all this time? While I am faithfully keeping my end of the bargain CellC is failing me dismally. Angisayfuni kwaleyofoni yabo ekade beyikutakuta mihla le, ngifuna ifoni yami entsha ebengilokhu ngiyikhokhela noma babuyise imali yefone esengiyikhokhile sihlukane ngokuthula. Ngaze ngadinwa!
