Cell C does not believe in Customer Service

This is my 3rd report in 3 weeks. My 6 month old Z3 stopped working. I waited 4 weeks for a replacement. I was given a refurbished phone that didn't work. The phone is completely blocked, don't know if it was ****** and recovered. What is the use of replacing a phone just to shut the customer up, but the customer is now more frustrated than ever. I have spent my December holidays phoning and running around to the cell c store just to sort out my phone. Although i was given the replacement phone in a terrible condition, i was willing to let this complaint go, but now I cannot use this phone as it gives an error code which cannot be unblocked. The staff at the Cell C store in Shallcross finally know what we go through when we phone their customer care number, there is absolutely no service at all. My phone was sent back to JHB 08/01/2016, once again the waiting begins. I will not settle for a refurbished phone. Please replace it with a brand new Z3. I am not willing to be inconvenienced any further. I will be commencing work on Monday (11/01/2016)and certainly won't have the time to be doing the running around. I must commend Lavinia - Shallcross branch for her assistance thus far.
