They are a collection - attorneys office out of Wyoming. They are collecting on bad debts. Ans have been nice to remove numbers when they no longer belong to who they are looking for. If you call the 800 number they leave during there normal hours you can talk to a live person.
DNC doesn't apply if they actually have prior business with you.
Also, cell phones aren't released to telemarketers. Trust me, we've tried to find cellphone numbers to market our business to, yet only landlines are released to us.
Don't you think that when these collection agencies call...it's because you owe somebody money??? Pay your bills and they'll stop calling. It Collection Center, Inc. from Rawlins, WY.
