Taking money, sim not active,nor correct device!!

Now this really take the cake!! When I receive an incorrect device from Cell C I asked them to take it back. They still didn't collect it. The sim card was not activated, but Cell C deducted monet from my account!! I was told by the call centre that my contract starts from the day my sim card gets connected. How must I use the data without a device?? Do Cell C so urgently needs money?? Call me asap!! I am not even officially a client, and I am already unhappy. How will I feel in years to come??
