I found two unauthorized charges on my credit card with companies that I did not recognize in amounts I could not match up. Upon further investigation and by googling the companies, I found similar 'canada-complaints.com' with the same companies.
These charges were supposedly for products that I had not received. Had I received anything at all, this would have been a "tipoff of the ripoff". The only product received was two small sample tubes of tooth whitener.
My credit card company has been great about it and has filed a 'products not received' and disputed the charges. We'll see what happens. It's important to get in touch with all of the ripoff companies involved (phone numbers received from my credit card company) and cancel any accounts, whether you set them up or not... they've got you on file!
