ACS debt collectors are a SCAM!!

I received an email this morning (7/11/17) from ACS saying I took out a $300 loan and never paid it back and I now owe $967. Anthony Hunt(the person who sent the email)threatened me by saying if I don't pay it back by the end of today, I will be laid off from my job, back listed from EVER getting another job, wages garnished, child support and income taxes will be held, PLUS a lawsuit will be filed. I asked him to send me proof that money was sent to me. All he could give me is the last 4 digits of my social and IP address. I googled the company and, as expected, thousands of other fraud complaints and NO website! I emailed Anthony back telling him what I found and he has not responded.
If you go online looking for a payday loan and begin entering information, there a people who can hack in and find out what you've entered. Then these people basically try to scare you into sending them money with threats of lawsuits, wage garnishments and even job termination! BEWARE!! DO NOT SEND THEM ANYTHING!!
