Who called from 4152313772

Appears to be spam - leaves no messages

I've been getting several calls a week from this number.  I don't answer and they never leave a message.

The call came to my cell phone while working on the company telephone.  I answered and disconnected - no follow up.

Call to my cell during dinner time; caller left no message

Called my cell. I sent it to voice mail. Received a text "can I call you later" . Now blocked. Tired of spam originating in my area code, but the 231 prefix is a dead giveaway for spam
