I had a call from this number whilst overseas ( at 3.40 am) . Somewhat annoying!

They have called 10 times over the last few days and left messages on my answering machine which consist of call centre background noise - irritating to say the least, as I have to listen to the start of the messages first before I can delete them...
Today's message said "Hi my name is Sonny, I'm calling from Premium. How are you going?" and then they hung up.

ON MY BLOCKED LIST

I called back number (03) 8687 4180 just kept on ringing no one answered the call and never got any voice mail.

(03) 8687 4180 - called but no answer.

Have rung 5 times today (didn't answer any), finally cracked and answered tonight, automated voice - 'you will be connected to your party' - background voices, just like a Call Centre, but nobody spoke, just hung up. Strange but now on my 'Don't answer' list.
