VODACOM NOT GIVING DATA I SUBSCRIBED FOR

I upgraded my package from Black Friday 300GB Day 300GB Night package to Black Friday Home 10Mbps 1TB Package. The app shows that I am on 200GB package. After calling Vodacom Customer Care, I am being told that I am on a 200GB FAIR USAGE Home package. Which is clearly not an upgrade. How can I go from 600GB to 200GB??? So I am told that I was misled and now I can't OPT for another Black Friday deal as all deals have expired. I spoke to Thato and he advised that his Supervisor "Vuyo Tselapedi" will escalate the issue
