No service delivery.

I called Vodacom in April asking for about my settlement for cancelling my contract which had about 5 months remaining. Spoke to Jabulani from the Retention department. He gave me the total cost and asked me the reason for the early cancellation. The phone i had on contract broke and didn't want to continue paying for it. He offered me an early upgrade which now they call it Migration. He informed me i'll be paying for the same old package with a new Samsum Tab4. The old package will continue until September and the new one will then activate in after the old package. THAT WAS THE AGREEMENT. Now i check my phone for the package, its not the old one but a new package. Called the call centre to find out why i'm being charged R1200, i'm told i'm paying for the 2 phones, the new package, Migration fee which was not spoken about with Jabulali, Prorata, and a Laptop that i don't have. They can't help me with anything until the invoice is sent, i can't speak to Jabulani or his Supervisor. How did i get from paying R418 a months to R1200??? Like Vodacom keeps playing games over and over again and they never deliver.
