Caller: I Don't know

same as all the other complaints above. Only can agree, the system is stuffed with these pricks calling. Just block and eventually they wont get through to anyone. My calls have dropped off dramatically by just blocking as they turn up. Major clue is the first four numbers plus the call tone! Don't attempt to call back, that could cost you a call
which maybe the only reason the call was made..........

Caller: Random

They called and when I picked up they hung up straight away. No response when calling back

phoned no message left. marketing?

Said my name and then hung up?

Spam

Think it was an outbound call centre, get a dead sound when ringing back.
