Not getting back to me on my account issue, that Vodacom has caused!

In June 2017 I phoned Vodacom cancellation department and spoke to a woman to find out how much it would cost to cancel the remaining time on my contract (Which was in 5months time) When she asked me why i wanted to cancel i explain that Telkom had a better deal for me and explained it all to her. She asked before she gave me the information of canceling if she could try and better the deal for me. I said sure fine see what you can do. She called back a few hours later with a deal which i accepted, one of the items she "offered" if i can say that is that my old contract would fall away and my new one would take over... To me this meant everything from my old contract is canceled!

My first bill i get from Vodacom after i did the early upgrade was that i had two handset installments to pay, my old handset and my new one. When i called and explained to customer care what was told to me they said they would log a call investigation and get back to me. This was on the 24 July 2017. Since then i have had one credit on my August account, but nothing more. No one has come back to me to explain what is happening with my account. And everytime someone does call me back it is to say they will forward it onto the relevant department and they will call me back with feedback.

This issue has been going on for 4 months now. I reply to the emails on almost a daily basis to try get feedback, and no one gets back to me. I have am quite fed up and no one there seems to care. What do i do? I can say right now when my contract falls due, i will be canceling!!!!!
