Received call from this number. Didn't answer. No voicemail. Called number back, got automated attendant and hung up after hearing "please stay on the line ... " Number now blocked
Just got a call from them today at 10:08AM, called them back at 2:50PM and an automated voice responded with, "you've been connected" with what were harsh digital scratches to follow. I waited in silence for about 20 seconds until another automated voice had said, "you've been kicked from the conference" and hung up on me.
