The \Vodacom Family\"? What a joke"

I have 2 data packages with Vodacom - one since 2007 and the other from 2012. I am trying to cancel one of them - I have had 2 call centre consultants hang up before even speaking on the phone. I have had 1 Consultant tell me someone will phone me back in 15 minutes (2.5 hours have passed) and another 2 Consultants who say I have phoned the wrong number (even though it is the number they have given me). I have a good mind to cancel both contracts while I am about it - the service is awful and I have been on hold in total for more than 2 hours this morning. the welcome message \welcome to the Vodacom family\" - what a joke.
