I also got a call on my mobile from this number. They must be the ones calling my office line (no Caller ID there). I may owe Capital One, but I'm current on my bills. No need for collections on me. I think I went over my limit once in the past 6 months which I took care of via their web site.

If this really is Capital One (or related company), I *WILL* close my account when the card is paid off.
