Branding change needed Cell-F more appropriate

Do people still take out Cell C contracts? I am meant to be a VIP with them and have been willing to over look the constant call centre spamming and lack of cellular reception for my regular upgrades. Lo and behold, gentleman assists me with an upgrade today and verifies me at the beginning of the call. Five minutes into the call has to do the verification for the actual upgrade and again asks me a series of personal questions that only I am meant to know. He tells me I failed because I only got 50%. He cannot tell me how I failed and I am flabbergasted because they my questions. We try the exercise again. Different questions even easier. This time I get 65% but it is still a fail. However the questions were so clear this time that there could be no doubt that I should have got a 100%. He calls the supervisor on my request and she tells me nothing she can do it's the system but I mustn't worry they can do this whole exercise again tomorrow. I tell her rather to cancel my contract and let me move onto a more serious cellphone provider. She gives me a whole host of instructions that I need to do. Time for a branding change Cell-F.
