I have blocked other numbers with this caller ID. No messages left, calls late at night around 9:00 PM. It is located from Columbia, Missouri. I will add this to the block caller list as well.

Received a phone call from this strange number . I looked it up and it looks like its the collection agency called Amcol Systems. No clue why they're calling. Can someone confirm that it's really them?
