Djr Group nigra capital Pay day Loan Scam Internet

I got a call today from Nigra Capital sstating that they were just call to see if I wanted to take care of a loan I took out in 2011.  I didn't know anything about. I had in the past taken out several but have since paid them all back. but these guys say I over 600 dollars and and i have been doing some checking and cant even find any thing on them. I even went so far as to look up the company they say they represnt DJR group and tried to get into there web site and they had no record of me.

So About ten minutes after I got that call I ot a call from something Called LAM Sevices saying they weee bringing me a subpeona. that they had a docket number for me and everything and if I called this other number I could have that halted.

I have never heard of any of these people.
