Upgrade Nightmare

I have been a very long standing customer with Vodacom and I have received the worse experience ever. I am trying to upgrade a line to a R699 package. However Vodacom says to me that because of my Debt Review I can only take a contract of R1300 - how does this make sense? I called customer care, got terrible service from Anele who just kept quiet on the line, then she referred me to Accounts who said they have no clue but everything is fine on their side and sent me back to Upgrades - this after I told them that I already spoke to an upgrade consultant. The professional answer that I have received is they have no clue. Finally they send to me acquisitions who of course cut the call and ask for an IBR number which I know nothing about!!!! What is going on Vodacom??
