Unauthorized deduction form onair TV- *****ulent activity from onair tv

These people are ******, I have been receiving calls from them but each time I asked them not call me again as I do not want their products. Saturday I saw a deduction from them on my account. I don't know what it's for as I have not spoken any further with their consultants other than for them never to call me again. This is pure *****, deducting money from one's account without their consent or authorisation and without any service provided or product offered
