Based on what everyone has said, I believe this is actually Chase. I AM overdue on my Chase Amazon payment and received a call today. I'd assume that anyone who doesn't have Chase/isn't overdue is being called because the real person who is overdue put in a wrong number.
Chase Bank Collection Dept. I actually was about 20 days behind on my payment because I forgot to finish the online payment. I didn't hit the "Schedule" button that was below a bunch of comments. They should be sure they have that button viewable. Poor website design.
I received a voicemail from this number in regard to my Chase account. They left me a message to call Chase number of the back of my credit card. This is a scam.
