CORRECTION: This call came from 707-367-5875, not 5668 (posted on wrong page), but it seems like a typical type of call as 5668 ... when I looked up the number before posting this, under # 707-367-5875, it brought up this page for number ending in 5668. FYI.
Woman called on a Sunday and asked for me by first name. I then asked who was calling and they said "is this "my name", do you have time for a short survey ... I said "I'm on the DO NOT CALL REGISTRY and then they hung up. I tried to call the number back and it said it was disconnected. Call came in as noted from Ukiah, CA #.
