Im also wondering about these people as my mom got a phone call from them.

A female calls my place of employment claiming to be Powell Law Office and the number they give me is a Denver phone numeber and when I do a search online for this firm, they are located in Indiana? Seems like they are scammers. They request for me to call back in an hour regarding a "file" they have on me. They do not give me the name of the client they are calling for. Not sure they are for real because I never received any paperwork regarding whatever debt they say I owe.
