Caller: Female with asian accent

Called twice today, first time claiming to be from SVI Coin, the second time claiming to be from Security Exchange Commission in UK. She already had an old email address for me and did not have an Australian or British accent. Said I have unclaimed investments from Crypto currency from years ago, i have never invested in Crypto. The first time I googled the company which did not come up, she wanted to send me a link to prove who she was and hung up when i asked questions that were to hard to answer. Second time I hung up after she could not explain why she was calling from a NSW number when she said she was from UK.

claiming from Australian Securities and Investments Commission. Not an Australian accent.
Then wanting my email address for his 'company'. Said I have unclaimed investments (which I dont).
When I called him out and asked questions, he said I was obviously not interested and terminated the call.
