Matching Black Friday Special

Phoned Vodacom on 23/11/2018 to enquire about cancellations. I spoke to someone in the retentions department who asked me why I wanted to cancel. I informed him that Cell C had an incredible Black Friday special for R179.00PM (J4 Samsung...90min,90sms, 500meg data) and I was looking at it as Vodacom had nothing similar and I had just ordered this special for my son as well. I have 3 accounts with Vodacom and have been with them for over 20 years which we also talked about. He asked what he could do to keep me as a customer and I mentioned to match Cell C's offer...which in a nutshell he thought was possible and would take it further and keep me updated as he would also verify their special which he did. We are now on Tuesday and I have heard nothing from anybody at Vodacom and this really worrying to me as I don't know if he was been honest or was just playing me along. No reference number was given for the call but I know it was recorded as per the norm at about 11:30.
