I used Intelius to get information on a telephone numbers that was on my cell phone, they could not find any information and said no charges would be put on my credit card. The next month I seen a charge for $19.95 for some type of credit card protection service that I was not aware I had agreed to, after calling Intelius they said on the second page of the agreement was the part about the protection sevice.
They said they would cancel the rest of the monthly charges for the service but not the initial $19.95.
I just called my cedit card and disputed the charge.
This type of business is nothing short of scamming people by sticking some service in the fine print which they know that few people ever read.
