Voice recording said they were from Telstra & my internet was going to be cut off if I didn’t choose an option, I hung up as guessing it’s a scam ?

Just received call from 0454533218 voice recording claiming to be Telstra and that my internet is being cut off gave me option of pressing 1 to keep my internet or 2 to delete it
Just hung up on the call
Of course tried to ring Telstra but you can speak to anyone anymore it’s all by messages and still waiting on a response from them ...
seems to be a scam number can’t call it back either
