2 calls back to back here as well. I just hit talk, then end...and they called back right away. Same deal. I was working on something, and didn't want to be bothered. I have no idea why I even pay for a landline any longer, other than cell service is spotty here.
These people are persistent. Tonight, I got 2 new calls back to back. First caller ID shows "Important Surve" and the next call, a few seconds later, shows "Not Available". I'm starting to question why I even have a landline.
