I received a call on my mobile at 12.15am on 29/05/2014!!! I answered thinking it could have been something important, but it was a prank call the bastards! It was a robotic voice that exclaimed "Good Tidings!" and then hung up. Other complaints above have mentioned 'Hello World'...maybe it was that...I was tired at that late hour. All I can say to these miserable human beings is... "Karma scum bags, karma. It will bite you in the arse big time".

Also got a call 28/5/14 at 9.51 lasted 7 seconds

Wed 28/5 at 8.45pm strang voice and then just hung up

Same as above - woke me up the pricks
