Received a call from 424-226-0436, and did not answer. No voicemail left. I have a smartphone, and it has a handy feature to allow you to block numbers. When you get a call like this, look on your smartphone to see if there is a little "i" in a circle to the right of it. If so, touch the circled "i" and then scroll to the bottom, that's where you will find the option to block this caller-choose this, then just hit yes to confirm. I have blocked over 30 numbers this way, and haven't received a call from the blocked numbers since I blocked them.
Call hang up at 705 pm PDT on Wednesday, May 20. Definitely a scam and a surprise they have not changed their number since starting this in August 2014. If number has been reported to FCC enough, could be getting closer to catching them.
