i just got a call too, same message as "Feb 24 2010" however I waited for the prompt for selecting "2" that discontinues whomever it was from calling me again. not sure this helps.
Same thing. Had a call from (877) 332 - 9017. didn't answer since I didn't know it. 2 minutes later, got the call from this number. Again, didn't answer since I didn't know it. Maybe a coincidence, but that was 2 odd calls in 2 minutes. The funny thing is, I've never had a credit card!
