Caller: Claimed to be from Koinly

Claimed someone had opened a crypto currency account and I had $100000 in it kept wanting to get more details from me. I demanded a statement sent to my email obviously a scam

Claimed to be from koinly.io and wanted access to computer to prevent a fraud they had "detected". Claimed someone was trying to take funds from Superannuation account. Mentioned something about blockchain privileges. Also had correct email address. Kept calling numerous times after I declined their "assistance " trying to re-engage.
