Got a call from this number 3 times within one hour.

i answered the phone and it was silent i kept saying hello but no answer and then they hung up.
I could hear them doing something in the background.

Its 'National Hearing Care' - just called them after they called and simply hung up, i have now added their number to my PBX's 'block list'

Call from (07) 3018 1190 on 7th Feb 2011 11:41amI answered with my business name and No one spoke from the caller end, I heard people speaking in the background, so I hanged up.

Receive numerous calls from this number and when I answer they just hang up. My number is suppose to be silent I'm not sure why I pay for it now.

This number belongs to National Hearing Centres

hung up when I answered, didn't have tim eto google this first!

National Hearing Centre. Young female caller, who couldn't understand why I laughed when she told me the company name, and I replied "Isn't it a waste of your time and the boss's money for you to call deaf people?" She also had trouble understanding what the Do Not Call Register is.

I got a call from this number, answered with a simple 'Hello?', then a man sneezed, and they hung up.. Not the first prank (?) call we've had this week.
