Lack of feedback and promises not kept

<p>I upgraded my son's cell phone contract at Vodacom Menlyn on 10 November 2016. A part of the new contract entails a R2000 voucher from Woolworths that Vodacom advertised at the time. The agent that assisted me informed me that they have a backlog on the Vouchers and that he will discuss with management and get back to me. I have requested feedback on this as well as feedback pretaining to my contract via email but to date no one has responded to give me any feedback on my query. Why does Vodacom advertise specials on upgrades that they cannot commit to? The lack of service I received is shocking and not even to talk about the unfriendly staff.</p>
