this number phones me nearly every day when i am out

this number keeps ringing me at 11 oclock on a weekday so i  presuming its a company.  they never usually never leave a messaGE BUT TODAY LEFT A message on my answer machine in the voice of that guy from phone jacker and said "good evening madam, i am calling from your building society" and now i know its a hoax. i would love to throttle the bastards

They call twice a day - I just answered to be told it was a personal call for me from IJL - who the hell is IJL I am fed up with them calling.  The man on the phone was from Liverpool so it is possible that is where they are based.  Is it possible to bar their number?!

This number rings my company every day. When we pick up they put the phone down. It is so annoying, I wish someone would speak so I could give them a piece of my mind.

They always ring me at 11.22 when I'm in school asking for Nigel Fletcher. I dunno who they are or what they want. But they speak to me like I'm stupid. I could quite easily scream at them. You know, I think I will.

Who was this and why did they call.
