So far I've found out that they go by at least 2 different names: 1) Premier Recovery Group or PRG, Inc., PRG LLC  2) Frontline Asset Management. They are a debt collector and claim to be hired by Cash Net USA.
DONOT under any circumstances give them any information. A legit bill collector would be more than willing to send you any info regarding a valid debt in the mail. Also they would not ask you for your personal information, not even to verify it.
Get as much info as you can from them: the name of the person you spoke to, their address, a phone number, and reference or case number if any then report them to the authorities because it is a SCAM

These are the phone numbers I have so far for them, I will update if I can get anything else:
1) 716-335-9947        2) 877-816-0564

Ive been receiving the same threats saying i owe a bill of $950 from CashNet! Ive never applied for a payday loan nor have i ever recieved any information FROM Cashnet saying i owe them anything. They keep calling threatening to take me to civil court!! Ive notified my lawyer as well. THIS HAS GOT TO STOP!
