After reading the said scams this number is good Alianz Insurance.
I asked them to confirm my Email
The email was right considering I used a different one from my own.

Absolutely legitimate number. Calling about my claim due to weather event in SA.

Caller: Alliance

Confirmed as Alliance Internal Assessor's number.
