Caller: A scammer

Someone spoke overly fast about liquidity in stocks or something like that - didn't apply to me so figured it was a scam

I got a missed call from this number but no message was left. I tried to call back and it didn't work, seemingly the number was disconnected.

Caller: No idea.

I’ve had a couple of calls from this number and another number with a different last 2 digits. They never leave a message so I just block them.
