Caller: Dont know

When I called this back from a private number I got a recorded message "thank you for calling Bupa workplace health solutions". Considering I have never had a BUPA account/policy and they called my private number (not the workplace one) I'd say it's a phishing call. Another one to add to the blocked list (and I'm on the Do Not Call register so they're cheeky bastards).

This number phoned me. Indian sounding man stating he was from Telstra and my internet was being used by unauthorised outside parties . Wanted me to get onto my computer and he would show me how to block them.
Told him I was at work and couldn’t access computer. I rephoned the number back and it had the BUPA workplace solutions message. I’ve now blocked the number.
