Yesterday I received a call from XXXX at XXXX stating that my name was part of a complaint filed and I would be getting served. I needed to make available someone willing to sign some documents on my behalf. She said she was with a law firm. 
I called back and spoke to XXXX. She said I was being sued by check into cash for {$220.00}. Docket number XXXX. 
I told her I paid this debt last year/early this year. She stated I needed the letter. I told her to give me some time to pull my bank statements but that I never received the letter. 
I pulled up my records ( written and bank ) and saw where I paid {$100.00} every 2 weeks to XXXX XXXX XXXX. With the final payment of {$110.00} being paid on XXXX XXXX, 2015. I spoke to XXXX about this transaction. The number on my statement is XXXX. 
This morning I tried to call XXXX and no numbers work so obviously, I believe I have been scammed. 
I called XXXX this morning to ask her the name of her firm. She said XXXX Law. I asked if she could tell me the court the summons was filed in. She could not. I asked her who the process server is, she could not tell me. Her ext. Is XXXX. 
She asked for my email and said she would look into it. I gave her an email I do n't use. 
Now, I have to research XXXX and XXXX and hopefully can recoup my monies if I was scammed. 
Please look into both companies.
