Who called from 4085003109

I didn't pick up and they didn't leave a message.

they call every freakin day until i finally called back and there looking for someone else lol.. what a bunch of [***].. rickenbacker collection agency

You answer the phone and there is silence on their end.Then it just disconnects. Almost daily.

Fake collection agency.  An automated voice asks me to press 1 to validate my name and then requests payment for fake debt.  The number continues to call back multiple times a day.

I have had similar experiences to those described by others. Please also file any complaints with the FCC to get federal assistance with this issue.
