VODACOM STAFF ARE INCOMPOTENT

I am so frustrated with Vodacom. I have been in contact regarding the cancellation of my contract. I was contacted by an agent last week, after complaining on LinkedIn. The agent advised that they will allow cancellation with no penalty however a consultant would contact me. I specifically informed the agent if cancellation will only be done after the consultant called me and he confirmed that was correct. My reason for asking is that I had questions I needed answered prior to cancellation. I have received no call. I got an SMS this morning to say I would receive a call. Nobody called and now I get an SMS advising that my contract is cancelled and I need to use my minutes before NOW!!!!! This is the second contract in 2 months that has been cancelled without final authorisation from me. What is wrong with the staff at Vodacom? I want my contract reinstated and to be contacted immediately as to when the cancellation can be effected!
