Caller: I don't know

They left a message "hello" with an accent.
Then hung up.

Caller: "Global Economic Forum"

Its an personal info gathering call dressed up as a survey.

Caller: I don't know

I was in a meeting and this number called 5 times and didn't leave a message. After the meeting, I called this number back, and it is a disconnected number. Obviously a scam call.

Scam

Caller: Survey

Asking to do a Economic survey…I answered to a couple of questions with no, then they asked me what my income was..I hung up

Have answered two calls from the above number.
Nothing said, it/they just hang up.
Now blocked.

Very rude, even called back to hurl abuse

2 missed calls, no answer when I call back

I got a call 3 days after the 12th April but after letting it ring out no message was left as I requested so I checked here. The number has now been blocked!!!
