Contract entered into **********ly

An amount of R669 via debit order has been going off my bank since start of Dec 2014. When I enquired about this by phoning ***, they said I must go into a vodacom store to sort out the problem. When I went into a number of stores, each told me that I had to phone a number as they cannot help with account issues - therefore two different stories via two different channels - by phoning I have to go into a store and by going into a store, I have to phone. Vodacom has allowed a contract to be authorised without my knowledge, & delivered a phone without me having received it. I wonder how this happens, because when I have to request anything I have to bring so many documents along just to prove that it is me. 1 store tried to assist me & gave me info re contract start date & delivery. Only thing is, I never entered into any contract. Secondly I never even received the phone. This is *****. I want all my money back (from December), including interest. I would like a copy of the signed contract (because on delivery one signs a contract as well), & if it was telephonic, I would like a copy of the recording.
