bad service

I took in my gear for repairs as it is on warranty, Samsung picked up that it did not match the one noted on proof of purchase, so I took it up with cell c manager, he said he will make a plan. he got me a new gear noted on the proof of purchase, but it could not connect to my phone, I notified him and he said he will make a plan again...it has been like 4 months now this matter has been going on, I have to follow up with them every time to get feedback, and service I get is not fair as I have to use my money for transport and my energy and airtime to do all follow ups, I live with no watch it's not manly...the service I have been getting from cell c is nonsense as I'm a paying customer but I'm treated like I'm nagging, airtime vanishes from my phone I call customer care, they say they will revert with feedback but no call from anyone...I call Cell C Sandton city no answer, when I live messages for the manager, he does not return my calls hate the fact that I have one more year of contract with them but hey no choice right. thanks cell c for showing me how you really appreciate your customers mxm ?
