    According to the report, the number I paid to find out who it belongs to, says it doesn't exist, but, when I call it, I get a message saying the person you are calling is not available. Please let me know why your data bank says the number (720 477 3005) does not exist and please refund my money TY

    I have some reservation with your application. Initially when I order this I was told there was a base product $19.00 and an additional charge for the Premium reporting. I took that to mean one subscription for your services and one subscription for the premium, service. I would see $19.00 + $18.00 monthly as subscriptions rather than a charge for every report I process. I was just about to proceed when I read, Premium Reporting Now Only $18.00 - One Time Fee. This tells me it is not by report as much as a one time charge. It's clearly posted to the checkout. Regardless of the explanations you have repeated, clearly on the checkout it states "Premium Reporting Now Only $18.00 - One Time Fee". Will you be honoring this commitment of service? I would prefer this request get forwarded to the management level, and not have the Philippines help desk recite the same tired old scripted line over and over. Very Best. Brooklyn and Brian

    Well I called this number back and they are selling insurance so I asked them to remove me from their call list. Then I re-registered all of my numbers at w.donotcall.gov. Hopefully this will help.

    Something about getting quick cash or a loan. Included a "text STOP to this number" which I didn't do because it would just confirm this is a working number. Appears to be from the Denver area.

    This horrible man called claiming that he was trying to collect on a Dept. of Education Loan on a promissory note that I signed in 2009.  I never signed a promissory note in 2009 and all I simply stated was for him to send me proof as I wasn't going to give him credit card information over the phone.  He said that is fine and then he went back to asking me if I remembered signing it.  I once again asked him to send me proof and he started yelling at me that it was a stall tactic and I was just trying to get out of paying the loan.  I then told him to stop yelling me and threatening me or I was going to contact the BBB and he started yelling and threatening me again where I then hung up the phone.  I'm not sure who 'this' is, but I am certain that it is against the law to threaten in this manner.

    This phone number is listed for a 'too good to be true' residential rental in the Seattle area.  When I Google searched the telephone number, it comes up for 'too good to be true' rental listings on CraigsList all over the country.  Does anyone know more about this?
