3 missed calls in 2 hours - no messages left. I have 672 numbers in my contact list. I literally get over 100 calls a day. I don't simply return missed calls. If your number is not already in my contact list, then you have to give me a reason to call you back. Leave me a message! Blocked!

Here at an Adelaide business answered a call from this Sydney (????) number. No one spoke.....thought there was possibly trouble with phone lines but after a minute of no response to my hello's I hung up. Rang the number back....answered (stopped ringing) but no one spoke. Phishing ?
