Who called from 6515607030

I am getting calls since past month from this number with no voice message left.

Received a phone call from this number today. It was from a survey group asking "agree" or "disagree" questions regarding political viewpoints. Called from a local phone number but caller mentioned something about Virgina.

DO NOT CALL MY PHONE NUMBER ANYMORE

Caller ID shows this number as SSI. Did not answer, as phone rings as long distance, even though number is local.

Received this call today and they left a message. Said they were calling on behalf of Regents Hospital then asked if anybody was on the line and hung up.
