"I had the exact same issue with my voicemail not working and my calls getting forwarded to this number. I didn't recognize the number, I looked it up and found this site, seeing others have experienced the same thing."
Demands full dates of birth or SSNs before explaining the nature of anonymous, threatening collection calls.
"Called me several times would not identify the nature of the call unless I verified personal info. Duh."
Threatens jail time and account closure over jeopardized SSNs unless immediate payment is made.

Creates fake minute-by-minute urgency to sell warranties on brand new cars that already have coverage.
"This company has called me from many different numbers. They say my warranty is out of date and I need to renew. I tell them I have a brand new 2017 Toyota that I have had for 3 months with a 6 year warranty on it. Then they start talking over me."
