Why are scammers using 03 9003 4580 to impersonate Telstra?

Always verify unexpected billing calls by hanging up and dialling Telstra's official number from your bill.
What data overage charges should I expect from Telstra?

Telstra provides data usage alerts through your account portal and bill, which you can review anytime. If a caller from 0390034580 claims unusual overage charges, it's almost certainly a scam.

How can I block 03 9003 4580 on my phone?
