Who called from 7813138005

I have been getting phone calls from many different no.  I don't pick up the phone but they don't give up they ring again.

Calls from this number, but no message.  ID says "MASSACHUSETTS."

Called, left no message. Caller ID indicated 247 7 DAYS EMRG

Received 2 calls tonight. Did not answer them but no message was left. Googled the number and found it is from a dentist's office with the name Myers. . Apparently this dentist does not have a good reputation if he needs to randomly make calls to people he does not know and does not have the decency to leave a message. Think I will block the number..

Have gotten 5 calls from this number with no message. Going to block it.
