missinformed

so here I was booking my phone in for repair, was quoted almost R800, was than advised by the tech guy to rather go for an upgrade in less than 2 mths, as this will only cost me R150. Passed to an agent who still helped me choose a deal and pick out a phone, basically window shop. Went back to the store, was than told, oops, we made a mistake, upgrade date is actually the end of the next year. Not very happy, as I had bought a cheap phone till my supposed upgrade date. Later I went to the store to set the matter straight, spoke to the agent whom I have told that I would like to do a new account and would only pay the upgrade fee that was quoted. Termination fees was told to me yet again, for current account, would not apply, not the case. Requested a manager, she was extremely unsympathetic and suggested I call the call center, as there is nothing at store level that can be done, she actually went to the back office to get a recording of he conversation, however she came back and told me the mic was not working. After numerous calls to the call center, each actual y nd nd every person I spoke tot, would take ownership, and the only thing I got back was more miss info, no one is
