Got a call today. The caller ID shows "BRG RESEARCH". Further research showed that it's a market research firm with the website at http://www.brgresearchservices.com/. I am blocking this number.
Have called several times to my cell phone. Never left message. Calls are late evening, I am located on East Coast. Received and answered call tonight; when I picked up I heard background noise and said hello several times before being hung up on. Extremely annoying.
