I was contacted by phone by a man who said he was calling from a law office, and that they were collecting on a loan that I owed to XXXX. He said I owed {$600.00} on the loan, and with late fees over time, I now owed {$1300.00}. But then he said that he would work with me, and that if I paid {$330.00}, within 24 hours, then that would settle it. 
I did have a loan from a few years ago, and I did have as dispute with the lender, because they took more debits than they were authorized for, and so I did not pay them anything else, but had paid back much of the loan. I am not certain if the loan was with multiloansource or not, and I could n't find documentation to support that they were the lender I used. I have also gotten a lot of other calls from other debt collectors who say I owe on a payday loan from online, and they all had things they said which made me think it was a scam. 
When I asked for information to be sent on the documentation of what was owed in writing, they said they could n't send me anything by regular mail, but that they could send something by email. They already had my email address, which I thought was strange. They also never identified themselves as to what company they were with until they sent the email which appeared to be sent from Integrated Recovery Services. The email was just a Word document saying that I owed the debt, but not any proof. I also recently learned that internet loans are void in my state, so I do n't know how they would freeze my assets, contact my employer and garnish my wages, as they said they would do. They said I had 24 hours to respond or they would take legal action.
