800-955-6600 Reverse Phone Lookup???

Keep getting calls to my residence for two weeks. The caller calls leaving no messages on my voice mail. I finally answered. A guy calling from Capital One was looking for Rich. I told him he has a wrong number. He hung up. Today my caller id is showing this number called again. Need a reverse phone lookup. Who is this that's calling me??
