Rang on our mobile.. Said "Hello World" then hung up on a Sunday morning ?????????

Just got this call. 8:40pm in May 25, 2014. Didn't answer it. Glad I didn't!

so annoying this kind of BS type call. should be illegal with jail terms for this crap.

Just had missed call. Didn't leave message. I called back and couldn't get through as number not connected.
Best not to try and call back as had advice that it can be international hoax and can cost a lot if you get through.
