Missed a few calls from them. "Unavailable" on caller ID

they left a message and said it was my bank and were calling for a problem with my debit card. I didn't call it back because I couldn't understand the message clearly, so I called my bank and said they have no idea why I got that message.

I just received a call from this number and it came up unavaiable and when I called it back, it was disconnected

I didn't answer because I was out of the room.I later called the number,781-393-6810 and the tri-tone message said it was disconnected

They left a message on my voicemail with 1-888-910-2500 as a call back number. It is a Card Risk Prevention company that services Charter One and Citizens Bank. I placed an online order and they called me right away to verify the activity.
