Been getting a call from this number now for about a week.  I'm on the DO NOT CALL LIST, and they keep calling.
According to caller ID, it's a credit card company or some form of one.  It's called, Central Credit.  They won't leave a message, hangs up and calls back the next day.  They're don't make a donkey of themselves about calling all day, but it's getting to be very annoying to call every day.  Seems to me if they can't get people to answer after a few days they would just stop calling.  If it's that important they should leave a message, otherwise it appears to be a telemarketer and I don't answer numbers I don't know.
