I signed up with Intelius to do a reverse phone lookup. It said the number was listed in their service, and for $4.95 I could read the information.
Once I put in my card information, I was automatically charged $9.90 and could not back out of the deal. When I tried, it automatically went into another service of their's for identity theft protection. It took a lot of tries to back out of this page.
Then I got an email saying it would take 48 hours to get the phone # information. I called my bank, and they said I could file a claim against the company, but would have little chance of getting my money back.
Don't use Intelius! They're a rip off!
