called me and hung up

Very strange call, seemed robo.  Went through one-sided conversation with omitted words, something like:  if you don't . . . we respect that . . . goodbye.

The caller didn't seem robotic, but may have been. They asked for the lady of the house. I said there isn't one (I'm divorced). Then the voice said something like 'Say again' or 'What was that?' and I repeated it. There was a pause of a few seconds, like they were dumbfounded, and I just hung up.

don't say antthin call back ring 1 time than nothing

This phone number is calling to do fund raising for the Pima County Fraternal Order of Police Lodge 20. I have called the number.  It directs you to a customer service department that can answer questions, help you donate, or anything else related to the FOP. Also, there’s information on www.pimalodge20.ning.com. Plus, you can contact them there with any questions or requests.
The FOP is doing a lot of really great things for the Pima County police officers and the people that call are trying to help them raise money so they can do even more good.
