Who called from 2064960950

So annoying bcuz I get soooo many calls from this # and many others from the Seattle WA area- I have blocked them, entered # on the don't call registry, etc!!  Ugh frustrating! Any ideas of what else I can try please let me know...thanks

Keep getting calls from this number and they never leave a message.

hangup.called them...not  working #

Caller just hung up when I said hello.

I keep getting automated calls from this number on my cell phone. It is a survey group. I hang up immediately. I wish I knew how to stop them.
