VODACOM FUNERAL COVER

I have a 2 x Vodacom contracts and ever since last month I noticed that Vodacom Funeral cover was added to my Bill. After phoning 5 x difference call centre numbers I was told that the funeral cover was activated by a cell phone...(what a load of nonsense) even if this was the case, surely someone should have confirmed this and to top it all, the call centre assistance don't know how to cancel it......where does that leave me??? VERY BAD CUSTOMER SERVICE......I am now waiting on someone to call me back and advise what is going to happened and in the meantime I am paying for something that I did not ask for!!!!!!
