National Litigation

I started receiving calls yesterday from an anonymous, intentionally blocked number. I do not answer blocked numbers. A few minutes later, my employer informed me that a person had called the front desk claiming that there was a complaint against me and that I needed to call 1-866-716-2078. To satisfy my curiosity, I called it and asked who they are. The man on the phone told me they are "National". After asking once more they said they are "National Litigation" calling because of a payday loan from Advance America I had taken out back in 2009 that was not paid back. He then proceeded to tell me that the company is threatening to sue in court for non-payment and intent to defraud, and if I pay immediately over the phone or make a payment plan, the court proceedings will be stopped. I told them that I will have to get help from family and will have to call back. He then tried to set up a payment arrangement, which I did unfortunately, until I can get help.

I have tried to get a mailing address from these people and they will not give it to me because "it's a security risk for our employees". I also asked for a website and they said they don't have one. These people say they are not debt collector but they are a litigation company. I haven't received anything in the mail from them or anything stating that there was a complaint filed against me even though they have my current address.

Has anyone else heard of National Litigation? Everything so far points to this being a scam in my opinion.
