Awful service from Cell C

I am absolutely disappointed and appalled by the ********** service I have received from Cell C. I had a contract with them for two years and within those to years I have had various problems with the device they provided me with. I had to take the phone back, I think for a total of FIVE times and every time I had to wait very long for the device to be returned from the repairers and every time I'd just experience the same problem (As they kept giving me a \Refurbished"phone). My contract has now ended with them and I have changed networks"
