Claimed to have "very important information about my Telstra account", I'm not with Telstra.
He asked for all my info, hottest he did have my name, probably from a data leak from somewhere.

Claimed to have very important information about my Telstra account, I'm not with Telstra. Asked for all my info, which of course I didn't give. He did have my name which I'm sure he got from something that leaked.
