I have been receiving calls from these people for more than 5 years. You can opt out of receiving the calls but I believe that is from the number that just called. I have received 6 of these call within the last 9 days and my caller ID has shown 6 different numbers. DO NOT release any info to these people. It is a scam.
This is the 2nd 971-*** call I received today. The 1st call came from 971-220-1005, another Scam Caller. Now a call from this number 971-217-9515!! I've blocked them both!
