Calls and leaves no message

I only answered because I was expecting a call from a local home improvement company - mistake!  Something about the firefighters blah blah blah.  Told him I couldn't help and hung up.

Called and didn't say anything after I said "Hello" 3times. Called number back and got voicemail. Gus's he didn't want to talk to the man of the house.

Man called and wanted donation and to send some packet to me and I politely said No thank you, and het hung up on me. I get this about 4-5 times a year. The guy will curse me or hang up. He has a funny sounding voice

Called me and asked for someone who doesn't live with me, I told him no he was mistaken and then he replied, "Well damn it!  I got the wrong number". Wish I would have known it was a donation group I would have let him have it!
