When phone picked up its a silent call. We are on the telephone preference list.

Tried calling me a couple of times, Both times they hung up when answering...Whats the point. Idiots

keeps ringing me, but i never answer it. its starting to get on my nerves how can i stop them. I,ve read other comments and they say when they answer the caller just hangs up, i have rang it back and its a voice mail scottish lady and it sounds like she is saying scottish power, then no follow up on this call and the line goes dead. I am not with scottish power, so how did they get my number and why are they ringing me all the time. im 34 weeks pregnant and im sick of my mobile keep going off all the time. what do i do?

15 times they have called and each time they hang up when i answer

Just hung up when I answered.
