received call several times in past couple of weeks; no message but I heard background that led me to believe it was a telemarketer of some type. I called the number and received a message indicating 't=Thank you for your call. I'm sorry no one is available. If you would like to be added to our do not call list please press 1 now or if you would like to leave a message please press 2 now". I am already on the national do not call and so I should not need to be added to their do not call. I hung up.
I'm getting a lot of these types of calls - from all over the country. I get the feeling these robo calls are intended to confirm someone answers and just by calling back or picking up phone gets your number on a large mArketing list. It's just so weird with so many in just the last 2 months. We are the Govt controls? Blocking appears not to work except for a specific number since they call with millions are area code combinations.
