Reverse the upgrade

I have a modern contract with Elite Mobile via Vodacom. On the 21/01/2016 I receive a call from one of the representative from Elite mobile upgrade department to ask if I want to upgrade my existing contract as is about to expire soon I said yes, she give me all the options I told her I want a Wi-Fi Router with data of 5 Gig she said it will cost me R279 per month I accept. That evening my Fianc?e bought a Wi-Fi Router which comes with 100 Gig per month. On the 22/01/2016 I then called Vodacom to ask them to reversed the upgrade they told me I must call Elite mobile to reverse the upgrade which I did spoke to Nomfudo and she told me she did send an email to Vodacom to notify them about the reverse upgrade.<br> <br> On the 25/02/2016 I got a call from a Courier guy to ask me if am at work my respond was I cancelled the deal on the 22/02/2016 am no longer interested. I immediately called Elite mobile and I spoke to Veronica confirming that Nomfudo did cancel the upgrade and send an email to Vodacom and I must call Vodacom to cancel the contract on their side as am no longer want to continue with the contract. If I called Vodacom they say I must call Elite mobile and verse versa.Please Help
