Here are two pages of links to (mostly government) sites in Canada and the USA were you can report phone scams, or learn more about them.

Look here first:

They called, didn't leave a message. Unsure how they got my cell phone number or who they are/what they wanted. All I know is that the number is unrecognizable and they didn't leave a message = spam.

Did not answer, do not know anyone in florida

Called at 6:40am. Obviously didn't answer because of how flocking early they called. No message. Blocked them.

Called my cell phone--rang only once.
