I keep getting calls and when my machine answers the caller (or robocaller?) hangs up. So I called back using *67 to see if it is a real phone# and I got a detailed 'your call is very important to us" machine asking to leave a message with their hours if I didn't want to leave a message and an option to be added to their do not call list (yeah, right) but with nothing identifying the company -obviously they don't want to be identified
