Upgrade not registered - No feedback

<p>I went into Vodacomshop in Vodaworld on the 13th of January 2017 to do my upgrade. A few weeks ago i got an sms to remind me to do my upgrade. I phone Vodacom and my upgrade was never registered - allthough i have paid and i did receive my new phone. I have emailed through the payment and my copy of my contact multiple times to Vodacom - they have not even ONCE contacted me about it. I am still paying on the old contract and I havent received my new airtime data and free minutes. My contract will be downgraded to PAYG in a few weeks if this isnt rectified. If that happens, i surely might just as well got to a different service provider - with the new iPhone i got from Vodacom in January.</p>
