Same thing - I told him I wasn’t going to “verify” myself or my details until I knew who I was talking to. He then told me no - that I need to verify my details first - so I politely declined and hung up.

Caller: I dont know

Said he was calling for important matter, wouldnt tell me his company (07) 5657 9053) hung up on him

Called back and requested the company that called me and they refused to tell me due to “policy” until they knew who I was

I called back number (07) 5657 9053 spoke to a guy but did not say for what company until he verifies who I am.
