they are selling life insurance

They send you scams on sms through many different mobile numbers, if all sms doesn't work then they will ring you and then pretend that they know you.

Caller: No idea who they are

I answered the call and asked them who was calling, no answer, they just hung up.
Be careful, scammers try to record your voice to use it elsewhere

They are relentless. But when I answer they never talk. Good indication that they are time wasting scammers.

just annoying

Scumbags

They called me again and this time they used different number, that is (07) 3077 7430. Becareful, people.

calling and hanging up

Caller: Freedom Insurance

Really!!!

Caller: Not interested, didn't answer.
