Asked me to call back to 715-257-3217, ask for Rick Sullivan, they need immediate payment to stop court proceedings on a old debt. The law says debt collectors must provide a written validation letter by mail, which he refused to do. SCAMMERS

Received a call saying that this was a confidential matter and had to call back to stop court proceedings.  It said it was from the office of a Patricia Scott.

I had been getting a call from this person asking for someone who I didn't know. Then ironically months later they were asking for myself in regards to a "payday loan which I took out in 2014 for a cash net". This is where I drew the line and in return had to ask for his information which he provided: Client Services Settlement Agency 3451 Harry South Truman Blvd St Charles MO 63301. I explained that I never took out anything of such kind and explained it seems there's some fraudulent activity on your end. Then asked why would you call from a local number and be based out of MO? No answer could be provided and he said I'll just send the information back to the original creditor. I asked for the creditor's information so I can contact them directly and he wouldn't provide me with it and just said thank you and hung up. Complete Scam!
