Enticing retention package dishonoured

I upgraded my Vodacom contract in May 2015. I was about to switch to Cell C,<br> who offered me a better deal, when Vodacom retentions offered me a Smart M with 100<br> free minutes and 1 Gig extra data. I have a quotation for this, and their<br> team leaders have listened to my conversation with retentions, which<br> reflects the same.<br> <br> Up until now Vodacom has not given me my free minutes, and has been<br> charging me extra every month. After complaining many times about this, I<br> have been given my data allowance owed to me.<br> <br> Their consultants now tell me that the extra 100 minutes were onIy for Vodacom to Vodacom calls. There is no evidence of this in my quote or in the recorded<br> conversation. They propose to back pay me Vodacom to Vodacom calls. This is<br> not good enough. I still will end up having overpayed!<br> <br> I expect Vodacom to credit me for what I've been overcharged for, and to supply<br> 100 free minutes to any number for the rest of my contract, as well as 1<br> Gig data - as per what I was offered.<br> <br> I thought that having it in writing AND audio recorded would be sufficient to resolve this. Apparently not! My advice, disregard any enticing retention package, and switch to a reliable service provider
