Fixing my fone

On the 31st December 2015 took my fone for repairs as it was faulty. It was just dead. I took a contract with them in April 2015. They did take my fone and am told it will take 14 days for it to come back. A week later they call me and ask for a proof of purchase which I don't have as I bought the fone online. Eventually I got the the proof of purchase after calling Vodacom. Took the fone there on Monday(18 Jan) today I call to check where my fone is as I got an sms yesterday to say it's on its way to the shop. To my surprise the fone is there and not fixed. Am so disappointed and the level of service I'm getting from Vodacom. I don't even want that fine anymore let alone the contract.
