Van Ru Credit Corporation - they want to speak to you about a "personal matter" but before doing so, they want you to tell them "only the last 4 digits of your SSN." If you refuse and press them, they will eventually tell you the address and DOB they have on file for you. Neither were accurate for me. I told them the same, and apologized and ended the call. I think these people are debt collectors who do TLO searches on the names of their debtors, then call everyone in the country with that name in an attempt to find the right debtor by your name.
