Called but didn't leave a message.  Googled the number, defensive driving company in Allen.  Most likely a sales call.

Didn't answer call from this number.  No VM Left.  Caller ID Said "Tom Castleberry", but like post above, looks like telemarketing spam.  

called a number of times, left no message.  was told this is a telemarketing call.

Received call from this number a couple times a week, when answered they ask someone who is not known to me. After informing them they always say they will remove my number but they always call back.

called and left no message.... states Tom Castleberry of Texas
