Caller: They refused to say who they were,

just a Indian accent saying I need to up date my modem or Telstra will cut of my internet, I'm not a Telstra customer

Received a missed call from this number, didn't leave a voicemail message and didn't text me to inform me why they called. I called the number and it won't ring 🙄

Caller: Didn't introduce themselves, asked if this was (my daughter)

When I said it was her father they hung up.
Indian accent with background noise that sounded like a call centre.

Came up as a possible scam/ fraud call. I didn't call it back to check. Blocked and removed from phone.
