DJR is a Scam, Internet

I went online to try to find help w/ some financial issues about 8 months ago.  I went onto several Consumer Credit Counseling Websites, Check Loan Websites, and Short Term Loan Websites to just see what the best options would be. I never signed anything, I never approved anything, I never, gave permission to deposit money or withraw money or even went onto DJR Groups website.  But then 2 days later I have a extra $300.00 in my Checking account. 

Checked into w/ my bank, and they said to check w/ DJR.  I never was able to find a phone number or anyway to get in contact w/ them other than to get a loan.  Then 2 weeks later $50.00 starts coming out a my checking account. And that happens for over 3 months every 2 weeks.  So I'm pissed off, I'm still not able to get a hold of anyone at DJR Group to cancel the loan or find out what happened. 

So I closed my Checking account.  For the last several weeks I have recieved messages on my voice mail stating I need to return a phone call w/ important information pertaining to some Medical Agency, but when I call them back its Kramer Assts, and in regards DJR Group.  And they are requiring me to pay them $575.00 today, and if I don't they will take me to court, and also threating me with involving my job, and threating me w/ knowing all sorts of information about me.  I don't like this, I don't like to be threatened.
