Called left no message.

They're a "Breast Cancer Donation Center". Here's how the script goes and how to avoid their questions:
Them: Hi, is Billy there?
Me: Which Billy?
Them: .... Is Billy there?
Me: What is Billy's last name?
Them: Well maybe you could help me. I'm calling for ________.
Me: Which Billy are you looking for?
Them: Is the lady of the house there?
Me: Which Billy?
Them: .... Ok I'll update our records.

Their only job is to cold call, yet they can't seem to overcome objections. Jokes.

They Just Called. I do not answer these call unless I have a caller id name from my personal contacts.

I pretend to speak only Korean. That usually does the trick. Hahahaha!!
