Lies, stalling returns, giving out personal info without permission, charges without permission

Vodacom agent phoned with great offer for which nothing would be charged until I have inspected the goods and contract arrangement and AGREED to the terms. I could also transfer my exiting contract. If I was not happy, they would fetch the package without any charge to me. What really happened though is that I could not transfer my existing contract and would have to pay to get out. So, I declined the new offer which had by then been delivered. I have not opened the package and have been struggling for almost two month already to get Vodacom to fetch the package and refund the charges which I had never agreed to. They also gave my home number to the couriers without my permission and now keep blaming the couriers. Every time I phone they promise to instruct the couriers and to send me a tracking number. Not even ONCE have they sent me the tracking number they had promised. They continuously promise without doing what they promise i.e. they LIE.
