Claiming from telstra Internet

They claimed to be from Telstra. She could hardly speak english. It sounded like a call centre in the back ground

caller hung up when call answered

Female told me my Telstra internet had been hacked... I don’t have Telstra internet.
I told her she was attempting to scam me, she got angry and said I’ll disconnect your internet. I said fine do it! And she hung up on me.

I got told he was from Telstra and I needed to push 3 different keys to reset my Telstra line

When I picked up it took a while for the line to connect, and sounded like a call centre background noise, so I hung up.

Sounded like a scam but may have just been a wrong number. Caller claimed I had overpaid something by $100. I told her she had the wrong number
