Privacy Protection Plus- Memberworks Privacy Protection Plus, Memberworks - Another Ripoff Montreal, Quebec

Memberworks Toronto On Privacy Report offered a card that would allow me discounts on various products. I told them I do not purchase anything over the phone so they said they would send me info out it in the mail.  There was no charge for this and I could use it for a month and then if not happy just call them and cancel it.
The package never did come in the mail but the amount of $20.95 appeared on my credit card with no phone number or address to contact them.  I was told the contact number to cancel was included in the package they claim they sent me.
I have found out since then this is their scam nobody gets a package mailed to them and every one gets ripped off for $20.95.
If HBC lets companies like this use their name no one will want anything to do with them.I hope to be released from the above payment.
