Thanks so much for the information.

If you KNOW you owe no money, or believe the call was from a fake debt collector, please take the time to read this:

He called and claimed to be a locator on his way to my home to serve me with a "claim".  He then gave me the number 877-585-3975 to call to confirm the "claim".  The person on the other line, claimed to be with Consolidated, but they also go by American Credit Resolutions, etc.  I was told that I took out an online loan with a company called Riverside, but this same number told someone else the city of the company was in Riverside.  The rep at the 877 number hung up on me after telling me "you've been notified". and then the "locator" called me back to tell me he was to proceed with serving me and when told I was not at my home address tried to verify my work address.  I told him since he was a locator, to locate it and then said good-bye and hung up.  He called right back and in a raised voice told me he had googled me and that I had been notified and hung up on me.  I have no knowledge of this supposed loan and have not been notified about any such debt.
