I am having a BIG issues with this company called

I am having a BIG issues with this company called DJR Group LLC who said I took an internet loan with them. To be honest with you I did not. I did put in an application with a local loan company online so at first I thought maybe they were affliated and they are not. So I never received a phone or anything until I closed my account. I kept asking for information in writing all they could send was a email with my information typed in it. Which could be bogus!! Then they sold my account to some company called Frontier FInancial who keep harrassing me saying I owe this debt. I tried to settle with them to get this behing me. That still asked for a ridicolous amount and I didnt agree to it. Now they are wanting to garnish my wages. I called them trying to speak with someone who would be respect and hear my side but they are so rude!! They were hollering at me- they would not even let me talk. They were like pay the money today or dont call my company anymore!! I called to ask for verfication for the debt because what they sent me did not look legit. There was no account number just a case number. So I told them to send me proof of loan and debt and they got mad. So I have no idea what to do from here. Pls help and I still owe the bank were they overdrafted my account. I really pray that you can help me soon!!! Thanks.
