they call then hang up...and then when you call them back there is no pick up.

it happen to me the last 3 days.  I think some computer programing is try to collect valid number for marketing purpose

Went to pick up and they hung up after 2 rings. I think they have called before, same thing. No message left, probably a telemarketer. I am on the do not call list

Yes, it called me several times already.  every time i answered, it hang up right away. and when i tried to call back it answered for 1/10th of a second and hang up on me....it won't a spot on my blocked-list.

This line has called and when I answered, there is no one there. As others have noted, when you attempt to return the call "The person you have called is unavailable." with no option to leave a message.

? Malfunctioning prescription renewal alert?
