Who called from 3024578499

I got a call and it says from "Card Services" in the caller ID.  they didn't leave a message.

I called the phone number back and it says its an unworking phone number and to call 800-441-7048.  When i called that number, it says its "Card Services" again and to wait for a representative.

it's bank of america (formally MBNA)

I received a call today to my cell phone from this number.  No message was left.  I called BOA to determine if this is their number - they confirmed it was.
