Caller: Indian call centre scammer.

This number is a legitimate Australian business, who an overseas scammer has used to come up in caller id.
The caller said he was from Telstra, and threatened to "blow up my internet".
I told him he was a fraud and a liar.
I redialled the above number to be answered by an Australian business.
This is not good enough.
We are on the do not call register, and it is just a waste of taxpayers money.
