They've called me so many times and I  have blocked them. Its a total scam because I owe nobody money and Ive lived in Arizona all my life. Never been to  michigan. Its a scam dont fall for it or give any if your info to them.

identical MO as mentioned about. Dear BLANK .  Blah blah received case to ... serve you .... Cite case number BLANK.  consider this your notice.  no name given by caller.

Enormous scam. So let me get this straight: you're gonna come to my work (lol--I got this call more than once when I was unemployed, ffs) and yet you a) do not provide a company name (legally required); b) do not have my name; c) cannot provide a case number; d) have not mailed me anything. Meanwhile, LEGITIMATE collectors (to whom (alas!) I LEGITIMATELY owe money) send me a monthly statement, know my name when they call, and always provide the legally-required statement "This is an attempt to collect a debt. All information obtained will be used for that purpose." But somehow I'm gonna call YOU back and give you my personal identifying information. Yeah.....nah, bruh.

Don't fall for it. Don't lose a minute's peace about it. It's a scam.

No company name, being sued, going to go to my employer if I don't call them back and refer to reference # they didn't give one, been retired for 12 years!
 Please come sue me, love to see a telemarketer face to face

I received the exact same call..that  if i dont call they will contact my employer  to be sued. And gave a reference number..
