Caller: Opti Choice

I received a call and when I tried to call back the answer machine advised it was a call from Opti Choice. I see a number of these calls being reported by various people.

No message. That tells me all I need to know. Blocked and deleted.

Caller: Optichoice

Missed calls from this number. When tried to call back a voice recording says it’s ‘optichoice’, a health insurance comparison company based in Vietnam.

Caller: Optichoice

Received call from 0485 903 008, I didn't answer - no message left.
I called back another call from Optichoice - I've blocked he number.
Continually getting calls from these people from a number of mobile numbers - I have blocked all the numbers so far - but I still keep getting calls from them on different numbers.......................very annoying

no message, that's a scammer
