Did recognize number , did not answer, no message left. Rang back recorded message "Due temporary services difficulties we are unable to connect you call. Interesting how number has surfaced after 11 years. Mostly likely a scam. Blocked.

I received a (missed) call from this number today. I live in the UK, but am holidaying in Australia later this year, was wondering if it was regarding my holiday...

Heavy accent caller, extremely hard to understand, sounded like they were offering some sort of package deal for gas & electricity.

They spoke in heavy Indian accent in a noisy background.
And they claimed that they were employed by EnergyAustralia and they said they will offer discounts to me.
If I agree to accept their offer, they then start asking me for my details such as date of birth, my passport no, my licence no, etc.
