This number calls me every day. Sometimes multiple times a day. I pick up and they immediately hang up or they hang up after five seconds. There's no ambient sound on the other end, so it's a robocall..? I get more calls per week from this number than I do my own family members. I blocked the number physically with my phone yesterday afternoon, but the phone still rings once before the block works. I'm beyond my wit's end. I've been on the do not call list since 4/29/06 and just filed a complaint with them for this phone number, for all the good it'll do.
