Theft

I signed up with On Air tv about 2 years ago. When the explore arrived I sent it back immediately and cancelled. They have now after two years deducted an amount of R115 off my bank account. After talking to them on the phone I was told that this was some sort of rescue box which was a free services for the first 24 months. Once again this was two years ago. Now all of a sudden they are entitled to go and make a debuted order on my account with out my knowledge. I am sure once someone has cancelled any contract then everything that came with the contact be cancelled as well???????

This is theft and I have told them I will not let this go until my money is refunded.
