Multiple calls from this number. We did not answer and they did not leave a message. We do not answer calls unless we know the caller's identity. How do we get them to stop??

called from this # as well as 863-213-1273.  ID says Women's Cancer.  Have blocked both #s.

Keeps repeatedly calling even at 9 pm

Received this robocall thanking you for a pledge of $20 no matter what you say.  Robo-call.  Don't answer

The number was identified as "Women's Cancer Center", Because it dialed my work number, I answered.  Otherwise, if they called my personal phone I wouldn't have answered, would have waited for it to go to voicemail, and when it didn't, proceed to block the caller. Auto-voice asked: "Is this (insert my first name, here)?"  I hung up immediately! This is one of those calls where they try to get you to answer "yes" so they record your voice response.  Then fraudulently use your recorded voice to say you "agreed" to certain terms and conditions which allows them to bill you for goods and services you didn't buy.  Was on last night's national news.  If you receive any calls which want you to confirm your first name, hang up immediately!
