Missed a call. Called the number back and after a few seconds I got three beeps. (not an engaged tone) and the line cut off, so don't know who they are.

This number missed call me twice now but didn't leave a voicemail, so don't know who they are.

Charity survey. Possibly fake

Someone wanting to talk to production regarding Color Management. If you try and ring the number back it says it disconnected so obviously fraud or scam

Caller: Industry of Info -something-

Called land line and asked to speak with my Boss (first name used).
Advised he was busy and asked if they wanted to leave a message and where they were calling from which the said they were doing marketing research for Industry of info- (can't recall the rest) and will try again tomorrow.
She was really polite and didn't hang up on me, but I can hear the others in the background so likely a scam- but was the most polite scam call I ever had.

Caller: I don't know

Charity call line

Lisa Collins from My Charity Survey.Com. Sounds like pre-recorded conversation (chirpy and bright) chatting to my machine, when I didn't answer to her question "how are you today" she said she sadly had to terminate my call. Oh dear.
