Sold contract by REWIND, no delivery!

I got a phone call from a Vodacom dealership selling me a 1GB data contract with a mobile router. I have not yet received the router which should have been delivered a week ago, and now I am beginning to think I am going to be charged for a product that I do not actually own<br> <br> Please can you investigate and cancel any contract that has been added to my account as I believe this to be suspicious and am not convinced it was legitimate
