Caller: Some sort of scam

Had missed call. Rang back from work phone and number is disconnected.

SCAMMERS.
The lovely sounding Australian man congratulated me for winning a competition I never entered and the reward was a $100 gift voucher to bunnings, coles or woolworths if I would provide them with additional details and then enter a zoom call. It seemed suss so I googled the name he gave (Lewis Group) and that's where I read other people's stories about entering the zoom call with an African man who attempts to get all your financial information.
This is 100% a scam. They will steal from you.
