Worst customer service and attitude!

I spent over an hour trying to get an answer as to why I cannot upgrade on my current package, I was told by Tsego that its because of my payment history, but I qualify for a RED Advanced package - which is DOUBLE what I am paying now. IF the problem was payment history, then it does not make any sense to offer me an uncapped package. I called the legal department, who then put me back to upgrades and Zama answered the call. She was very rude and told me I should call back as she cannot ask my security questions. I explained that I had spoken to Tsego earlier, to which she rep**** \ Well if you spoke to her and she answered you then I do not see why you are calling again". This is TERRIBLE customer service"
