I have had this marked in my phone as DO NOT ANSWER for some time.
Just a hint guys. Write the numbers down or save them in phone ID as DO NOT ANSWER. saves me so much trouble.

Ball breakers

"Mel" (possibly a subcontinental lady) called my mobile and politely asked to speak with the person who organises the fuel expenses for our company cars. I'm in the Yellow Pages... but still sounds like a dodgy scam!

As above. rings then no one there when you pick up.

spam callers..

Just answered a call from this number waited about four seconds and then it hung up.
Bloody time waster!

These people are so rude. They rang it went silent then they had the nerve to try and call while I was on the phone to the same number (i.e. trying to call me at the same time).

Message at this number says 'Salt World Marketing Services'
