I called back number (02) 8039 4611 reached IVR for Dun & Bradstreet debt collectors.

This f*cking number rings me approximately 2 to 3 times a week, always around the 08:30 mark, normally there is no reply when answered, however today a automative reply message, requested that "This is an important call, please contact this number before 8pm. then it disconnects, firstly I own nothing to anyone, secondly if it was an important call, why didn't the morons talk to me then, thirdly and final, I wont be calling these d*ckheads at all.
