Bad service of note at Vodacom

I am trying to cancel my contract and to my surprise it is a hassle. I wish taking up a contract is as much as a hassle like cancelling one. After so many years I never thought Vodacom will mistreat their customer. My contract was ending on the 31st July and I called in to say I want my number on prepaid again. They offered me value added services and the lady said I have 14 days period to call in and cancel if I am not satisfied. Of which I did call within the 14 days. I cancelled and have the reference number to the call. Today I wake up and I am on a plan that I did not agree to, it’s just an sms to let me know. I call in and the first consultant puts the phone done on me. I call again and a rude lady doesn’t want to give me a reference number to my call.
