Caller: Claimed to be from Telstra but just a scammer

Called saying from Telstra and that someone is trying to hack my network, had the same call earlier the same day from a different number. Exact same script and they dont like when you interrupt with a question as throws them off. Said they want me to log into some website and they will show me who is trying to hack my account and help me stop it, when i said I am busy and asked if i could call back they argued that it had to be done with them immediately and that if i called telstra no one else there could help me only them. So when i insisted they provide me a number to call back on they hung up.
