I don't like to insult people's intelligence, but come on! Why on earth would you believe this to be legit. #1) The ad you clicked on to go to the website selling this BS was a paid link. ANYTIME it is a link that the company paid for, they are trying to sell you something. #2) Yes, the website (consumer tips or something) is the same company as BOTH the "dental" companies. It's really just one company.
Ways to avoid this in the future:
Anytime you click on an advertisement where the advertiser has paid to be there it is either a scam OR they are trying to sell you something. There are no other reasons for someone to pay to be there. Unless it is a very large, well known company, I automatically consider it a scam. Not once have I been wrong.
Another not so brilliant tactic that is used:
A company buys a website called something like "Consumers Opionion/Tips/Help/Reviews/___fill in the blank". The site appears to be a free consumer review site not trying to sell you anything. Then they say they have reviewed 100's of work at home scams and only ONE was legitimate. Then they go on and on about how great it was. In the end, the ONE company that was not a "scam" was their company.
One last thing. Unless it is a well know, large company (we are talking the top 5's like walmart, home depot, target) anytime you are paying for a trial that will automatically bill you when the trial is over for $50+, it is a scam. Everytime. Not maybe. Not if. EVERYTIME. 1) They are hoping you don't notice the amount you will be charged 2) They are hoping you forget to cancel 3) When the above fails, they change their phone number or drag it on as long as possible so you can't file a dispute with the credit card company.
