vodacom not keeping to their promise as sent out via sms

early December I was contacted by the Vodacom Business Sales team, saying that they had viewed my recent usage and wanted to offer the Red Classic Plus unlimmited SMS 1200 min and 4 gb data per month @ R1299 and I recieved the SMS to confirm Then late December I was contacted again and offered the Red Buisiness Plus @ R1399 which I accepted and was confirmed with an SMS which offered - unlimmited SMS unlimmited min and 4 gb data per month @ R1399 It was made clear that this did not include a device, but that I could still continue with my upgrade on the device in January When I called at Vodaco Cape Gate I was told that they couldnt honour the SMS ans that I would have to deal with Vodacom Corperate - I sent and email to explain my complaint - I recieved an email back from a Fhulu saying that on 01/01/18 my package was upgraded to the Red Business Plus with unlimmited SMS 1200 min and 4 gb data per month @ R1399 I responded asking why the SMS confirmation recieved read unllimmited mins Again I recieved an email from Fhulu with the same response as the previous email??? Surely false advertising / selling if they cant honour the SMS ???? I have now asked for management to respond - let wait and see ??
