Contract cancelation

I am very ****ed with VODACOM!!! Sometime in April this year my whatsapp was hacked and as old as I am, I didnt know what to do. I went to a VODACOM store to get an assistance but I was told "there's nothing they can do". I then went into a Cell C store which is few shops away from VODACOM. I found a welcoming young lady who assisted me without any hesitation. It took her about 3 days to sort my problem despite me being a VODACOM customer. My contract was coming to an end with VODACOM, and I decided to cancel my contract and move to Cell C. In May I gave VODACOM my cancelation notice and I was told my contract will be cancelled in June.

In June I went back to the shops just to check if my contract was cancelled, only to find our that it was not cancelled. I was advice to give my notice again which I did and the agent from cancelation comfirmed that my contract will be cancelled on the 18th of July. On the 20th of July I then went to a cell c store to sign up for a new contract and port my number. But guess what??? Vodacom rejected my port because again my contract is not cancelled. When I called customer care they said my contract is not cancelled and I was given reference number '***'.

The agent I spoke to by the name of simon said they will check the recordings of my cancelation and someone will come me back within 24 hours. Till now I have not receive any call.

All I need is to get my contract cancelled so I can port my number out. I AM DONE WITH VODACOM and their pathetic service.
