New R99 contract declined

I app**** for a tablet contract online, the sales lady contacted me and offered me a Vodacom tablet for R99pm. I advised her I needed two, as I have two daughters. The application was declined and the reason was None Financed Account. When I asked her what that means, she says I don't know contact accounts department, I did that and they transfered me to collections. My existing account has never been in arears. Let's just add that in March I was upgraded, in September my line was upgraded, on average for the month of Nov I've spent nearly R800 extra on data yet I can't afford a R99pm deal. Vodacom service is becoming more and more ****py, customer service is out the door. Thus far I've spoken to 7 agents in under 30 minutes. All I want is two R99pm contracts
