this caller identifies himself as Greg and has introduced himself as a fraud investigator. He called me 3 times during the day on March 31 2015 and once on April 1 2015.  On April 1 he left a message that he was returning my call from the previous day.  I am unable to substantiate his claims that he is an investigator and the call falls into the phishing category.

This is a common ploy by criminals attempting to extort money from people by scaring you into believing that you will be criminally charged, go to jail, lose your driver’s license, have wages garnished, etc. all for an alleged or nonexistent debt.
Federal law (FDCPA) requires them to send you a letter (US MAIL ONLY) within 5 days of their first contact that contains their name, physical address, the creditor’s name, and the amount of the alleged debt.  It also must contains “mini-Miranda” telling you that it is an attempt to collect a debt and that all information will be used for those purposes.  The one other important thing that this letter must also have in it is that you have a right to dispute the debt within 30 days receipt of the letter and if you do so, all collection activity must be stopped until the debt is verified.
