Same thing here!

idk who this is but they randomly called me and i tried to call them but i got disconnected

It's First National Collection. I have no idea what this could be about.

DO NOT ANSWER FROM THIS NUMBER! This number just called me and recorded my voice answering Hello, then went to static and a very long beep. I could tell it was recording me due to certain little sounds made that are a dead giveaway. It's creepy and I will not answer from this number again.

Beware... The Better Business Bureau gives First National Collection Bureau an "F" rating. Read the complaints before you agree to pay any amount that they claim you owe:

FNCB has been known to use many phone numbers, using a fake caller id such as "LOCAL OFFICE", in an attempt to disguise its identity.
