me too!! I called back immediately and the number was disconnected??

Lots of calls from (02) 8019 1356.  Originally answered one and person said he "was returning my call".  Untrue no call was made.  Have now answered 2 of these and told them that no call was made.  Dozens of calls in last 2 weeks including 7 in last hour--none answered.  Same pattern with (02) 8117 3301, (02) 8117 3302 and (02) 9021 4520.  All started at same time.
