Btc 360 demise

I keep getting calls about recovering money from a scam platform called btc 360.

Apparently,some one year ago according to the person calling me i had an account there.

Honestly,i dont remember anything about it or what,if anything i did on that platform.

But the person apparently claims they are some sort of lawyer trying to recover crypto money for people that have been scammed.

Seems legit but i dont think i put any money there.anyone has any idea how to remember or do you think its all just an elaborated scam?
