Caller: 'William David'

Phoned and claimed he was from TELSTRA Technical division,
and that I had problems with my Internet ;
I rang the number they gave me back,
someone answered after while, and I asked for
the same guy who asked me to wait ;
after a long delay, there was no answer ;
As with 1914695116 ( who rang me back ),
I am pretty sure this is some scam attempt
by people of indian sounding voices ;
needless to say, when ( they ) rang back again,
I let the call go to answer machine, and no message was left.
