I called back number (02) 8873 0864 reached voice mail for a company called Colmar Brunton Paid Market Research.

What is this organisation and where are they getting my number from????

Colmar Brunton- Paid Market Research

This number calls at 8pm at night and doesn't leave a message. No way will I answer an interstate number at that time at night.

1) rude for calling late at night when I am winding down from a day at work
2) rude for not doing the right courtesy by leaving a voice mail
3) rude for continually calling when clearly I wish to know who you are first

All I can think is it must be a scam for someone to be so sneaky and leave no message, intending to catch you unawares while at home. Beware!

I called back number (02) 8873 0864 rang 3 times then goes to busy tone.
