What do I know? Not much. They call a few times every day, in case you pick up the phone, they hang up on you. When you dial back they tell you they are a research company, not selling anything, and if you want to “opt out†from their calls, go on their web site. I did that. Twice. I also dialed a number and asked them to remove me from their calling list and still receive 2-3 phone calls from these ******es.
