UPGRADE DONE WITH NO HANDSET PROVIDED

On the 22 July 2015 I received a call from a Vishen who I assumed was calling from MTN Direct to discover later on he was actually from an outsourced company working for MTN called Velociti. He advised I was due for upgrade. I advised I am not yet at 2yrs of contract. He said system showing I am. Asked to check with Manager and see if can be done as my current handset had been damaged by water. He reverted that can go ahead. I asked any additional costs he said just for the new contract and once off upgrade fee which we agree will go off end of Aug. At the time I was not properly advised on handset and what he was selling me? I requested all we discussed be emailed to me first which he failed to do. In a panic I called MTN the next morning and queried. I requested cancellation from a Nicole. I also called Velociti and requested same with a Sumaya. Which is a day after the call mind you i.e. way before 7 day cancellation right. Despite all this MTN very \quickly"renewed this contract and cut off my current services which I have already paid for in addition did not supply the phone??? *****. I queried with Vishen"
