Called back, spoke with a 'Julie' who refused to tell me what company she was calling from until she had my details so she could confirm if there was a matter to discuss.

Answered and they hung up straight away

Rang me twice so I called back on a private number. He tried to get my phone number to direct me to the right company to see who called me. I asked what company it was and he said idk because there are heaps of company’s here so I need your phone number to look at it for you and I hung up

the man didn't provide details why he called, just ask for email address, it is a scam

Caller: Credit corp

Wouldn't tell me who they were until I threatened them with Australian law requires they provide their name and business kept saying this to her and then she told me she was calling from credit corp did not give my details stand your ground people by Australian law they have to provide their name and company they are calling from

Perth based number, wouldn't tell me why they were calling or who they were. Told me my number wasn't in their system so they would remove it, however called again next day. Blocked and reported.
