Upgrade Nightmare

Upgrade nightmare I have multiple contracts with Vodacom. I received a call of an outsourced company doing the upgrades etc. on behalf of Vodacom. I was totally mislead by the sales lady with one of my numbers due for an upgrade, as she told me that I have been such a good customer for 20+ years and therefore I will receive a phone totally for free on that number. I did not choose the phone brand - the sales lady did it. The phone was delivered, and it is a brand I am unfami**** with and when I read the reviews on it, they were quite negative. Then I received my monthly invoice and to my surprise I now have to pay for the handset I had no say in. I am now paying for a phone (not my choice of a phone) and it has been an absolute nightmare to try and reverse the contract via Vodacom. Since all calls are recorded, I urged the Vodacom aftercare consultant to listen to the conversation to verify that the sales lady has totally mislead me. I am furious and I am not getting any feedback on the progress of my complaint either. I have no choice, but to go the legal way.
