Caller: woman with Indian accent

I had a similar call - a different number - 0427 559 140. woman with an Indian accent claiming to be NBN, same story. when I asked how I knew she was really from NBN she repeated my mobile number & said it was listed on my contract - contract is in my partner's name. When I told her I was not having this conversation with her, she hung up

Called claiming to be from Telstra saying that my internet had been compromised (I don't have Telstra internet). Mentioned a lot of details and explained something about my IP address having been targeted. There was a lot of background noise like a call centre. When I said I didn't think this was true and asked how they got my details they hung up.
