After a called from (02) 7239 3094 which was identified by my mobile phone as SPAM, and the phone did not even ring, about 10 seconds later a received a call from (02) 6848 6632. I never answer calls, only 4-6 people know my number. Anyway, after 15 sec the ringing stopped that's when I noticed the call and under the number the word CURBAN appeared.
