Vodacom charges for services not taken up

The usual call centre agent phoned me from Vodacom to offer me a data bundle package with a free router onto my existing Vodacom contract - which I recently ported to from MTN. Telephonically it sounded good and I opted in with the clear understanding that I have a cooling off period as well as if the package is returned unopend , I will be able to cancel without any costs.... This is the catch. I acted within the rules and the package was unopened and unused. When I read the fine print the deal was not as sweet as it sounded and I exercised my right to cancel and the parcel was collected where it was delivered.<br> <br> Now a month later I got invoices for the charges as if I activated and used the data bundle package - which I did not do.<br> <br> No to get Vodacom to correct their mistakes. It will take all my free minutes to get hold of them to sort this out!
