I do not answer unknown numbers. The caller hung up and left no message.  I know no one living in Maryland.

This number has called my cell phone twice this afternoon and no message was left.  I have no idea who it is, so I'm blocking the number so they can't call me again.

I didn't get a call, but a message stating that I needed to give them a call at t his number.

I got a text message from this number, your tax liability is past due. Failure to resolve this issue might result in your account going into collections. Call me asap Debra 301-6586964.

I got the same message as Hank.  some kind of scam.. I don't have any tax liability!
