"investigator mark logan" called and left this number regarding some debt situation or fraud.  yeah.  funny.  this is a scam.  don't talk to this idiot and for the love of god DON'T BE STUPID ENOUGH TO PAY THIS a-hole money.  of course he threatened to "call the authorities.  i said go ahead, and this fella, mark logan, hung up.  LMFAO

my advice if you get a call from this deadbeat, let him know you are in touch with the authorities and the FTC, and hang up.  

this is a SCAM.

he called a threaten her with a 10 year old loan she didnt pay, so my with though she was in trouble. payed him, now he called back on another debt, then hung up on her when he found out i was on the computer checking. someone need's to stop him

That "someone" is you, if the fake collector can be located within your national borders. There will forever be another phantom debt no matter how many times the crooks are paid. That's known as "reloading" a gullible victim.

This sounds like extortion dressed as debt collection. The agents' horrid threats are empty and their conduct is illegal. As early as possible it's critical to determine if your collector is domestic or yet another South Asian faker. The former you can sue into submission; the latter tend to be out of reach.

My notes from October 2011 on payday loan and "hot check" collectors are linked below.

sadly people get nervous when these guys call and then they pay them . They call me for a couple of days then when I dod not respond to their threats of serving me at my home or work then they back off for about 3 months then the whole cyle starts all ove again. these calls have been coming for almost 3 years now. Don't know why they do not get a clue. The fact that their phone number is always different makes it very hard to track them down and serve them.
