LJR Group LLC SCAM ARTISTS!!! Internet

Back in the  summer I applied for a loan online. As it turned out, the site I applied at was apparently a site to get you hooked up with a lender " best suited for me" .. or some kinda crap like that.  next thing  I know I have 2 loans direct deposited into my account that I neither approved or signed for.  I could not find any info on the DJR Group to send it back and in the meantime the kept taking out 75. and 30. EVERY 2 WEEKS!!!  My bank kept trying to block them and they kept getting around it. Finally we got them blocked. and low and behold.. NOW they want to talk to me!  The lady told me my payment came back NSF. I said "yes it did". " I blocked you from taking any more money out of my account".  I told her I never applied with them..never signed or approved anything. She e-mailed me a copy of my SIGNED application. :(  So I'm guessing whoever I filled it out with sent it on to who knows who. But .. legally.. it probably doesn't look good. 
Anyway I told her they put 250. in my account and I would pay her 250. back if she would be kind enough to provide me with an address I would send her a check. (they had already taken 180. out).
She stated that " a check was not an acceptable form of payment". I told her that we were  at an impasse then, because I had no intentions of providing them with my banking information.
Now I had a (I suspect a collection agency) calling from Lombardo, sullivan & Meyers. First her name was Nicki Goode. Very nice, personable, professional. Stated I owe 550.00!! or I am going to court.  I was going to pay it cuz it scared me..but I tried researching them and can't find them anywhere. The number is the Ft. Lauderdale/Hollywood, fl. area.  Now I have a lady (sounds EXACTLY like the other one) claiming to be from the same law firm..fraud division.. and I have 24 hours to pay or I am going to court for check fraud because my payment came back nsf. (I originally got a prepaid card to pay them and gave her a date when she could run it.) Then changed my mind.
I'm thinking I'm gonna just get advice from a lawyer. It would probably be cheaper than paying these scumbag scam artists!
