[BeStRaFe]

ok... it was 12:45... i got a phone call on my mobile......

i dont know if this was to my home phone or my mobile direct
as they both come to my mobile anyway....

the numer come up as " NOT AVALIBLE "

Good Evening Sir, Its robert from telstra here.
we are just updating you account information.
can you please confirm your credit card number.
i asked what one do you have.
he replied... i do not have access to that information sir.
i then told him i didnt have any services with telstra...
both my mobile and homephone are with other cariers...

he hung up on me.

im on hold with "3" at the moment trying to find out if they can trace who called me... i didnt pick the accent......

verry worrying!!!
