SHOCKING Service - Terrible Cell C Representation

I changed my partners contract over to my name. I took a Blackberry Z3 on the upgrade.Naeem sold it to be with great pleasure as did not want to lose a customer. We since discovered that the phone is faulty, the screen jumps when accessing messages as well as a short battery life. It is within 7 days that we are returning and we requested a replacement phone.Naeem tried to steer us away from booking the phone in. He also advised that due to the OBF policy, the phone could not be replaced. He gave us a copy of the OBF form and I pointed out that point 6 allows the stores license to replace the phone at their discretion, once an RMA number is requested. He did not give us an opportunity to get one. He became incredibly rude and argumentative raising his voice to us in store and kept calling for the assistance of the other store employee, Tauriq Essa. Tauriq, also became aggressive when I asked for his name and surname, stating its an invasion of his privacy. Naeem could not answer any of my questions and refused to give me the store manager's name, headoffice details or the legals department. He stated that we were dealing with him only, he is in charge. This is unacceptable.
