according to the FTC, a debt collection caller must give their name, a valid mailing address, and phone number and tell you who they represent.  If you send them a letter demanding they stop calling you, they cannot by law call you again.  If you yourself are not the debtor, but rather just someone the alleged debtor used as a reference, then the call is harassment and should be reported to the FTC

This is a debt collector who calls to harass anyone who knows the person they are seeking which in this case is not me, but they keep calling anyway

I got a call from this number a Ms. Sanders, she said she needed my home address and place of employment to serve something that was given to her office that same morning. I asked her not to call me and hung up. She called back 4 times, left a phone number 877-210-2181 and said  "you have been officially notified."  I googled the number and it's no business is listed.

pissed off!!  This company has called my cell 3 times in a row stating I have a claim against me with a number and an 866-752-1245 number to call back and ends with "you have been officially notified.

frustrated and annoyed..this company called me twice in a row and I have no idea who they are they just say i have been formally informed of an action against me with a case number.
