When I answered, it took a second to connect. A girl is singing, then says "Hello?" I say "hello" again, and she hung up.

Just got a call at 406PM today.  Caller ID said Out of Area.  I answered but nobody was on the line.

I answered and no one responded

I answered because Caller ID said Amarillo TX which is only a few miles from me and the call could have been legitimate.  The area code was the correct one for Amarillo.  It was a breast cancer charity.  I asked if I could take a donation to their office and said "you're local, right?"  She said "Yes, but we do everything by mail."  I said "Great, mail me the info" and hung up.  They didn't call back right away so we'll see if I get anything in the mail.  She did address me by name, but my number is not unlisted so they could have gotten my name and number from public records.  I didn't recognize the name of the charity, or she didn't give the name specifically.  I have been getting many calls recently with a city name and TX, and I think spammers are starting to spoof city names in the recipient's state.

Some lady keeps calling and says she is sleeping with my husband.
