They are a debt collector buying up old collections that by law can't enforce due to the statue of limitations many years old. They are out of Texas, just don't pick up the phone because once you do they know it's you living there and you will be sorry because they will hound you for ever.
Obviously a scammer. When they call and leave no message of who they are or at least who they are looking for, they are obviously phishing for a name or information. If I have to Google your number because you call and leave no message as to why you called and I can not find a legitimate business claiming to own your number.... you might be a phisher.
Scummers, -that disregards the Federal Do Not Call list and Fair Credit Act. - I have no written contract with RSGI and therefore have no obligation with them. If they're calling due to purchasing a bad debt in hopes of collecting.....hope they enjoy their purchase.

Incorrect.
If RSGI obtained your debt legally, and notified you using the method mentioned at the FDCPA site, and if the debt has not passed the SOL ... then they can pursue legal avenues.
