I have gotten 2 calls from them in 2 days. I keep  missing the calls and they won't leave a message

I get calls from this number everyday. Whoever this is will not leave a message so Im clueless as to who it is.

Called by this number four time today. Did not leave message. Had recently visited and sought info from craigslist. Is this possibly related?

It's frm World Financial National bank -a bank that we have a credit card with or did have & are late on pwyments. I know this because I called the number back and got a recording that said "Thank you for calling World Financial National Bank"

Have been receiving calls from this number for weeks now... every time we answer, there is no one on the line and it just hangs up... wish they would stop calling...
