Called but didn't leave message. Caller id says Shreveport-Bossier

Supposedly calling on behalf of firefighters. They called asking me to donate except it wasn't a donation. But it was a donation. It just wasn't a donation. I doubt they're for real since they can't tell the truth.

Caller says "Sam?" I say "No Sam lives here". Caller hangs up.

Called asking for Lena. When I said she isn't here may I ask who's calling they said we will just try to catch her later.

Called again today. Asked for me by name. Caller said he represented "professional firefighters" ( not to be confused with those "amateur firefighters"). I hung up.
