My Aunt is Being Contacted by Scammers

My aunt was asked by a friend to invest 10000 euros into bitcoin 3 years ago. Now, she is not able to contact her friend anymore so she tried contacting this internet "lawyers" or "fraud experts". They pretend to have tracked down her money which amounts to 1.19 BTC apparently being held by Samoa Commercial Bank. (My estimate is that she would have only been able to buy .42 BTC with her 10000 euros at that point in time)

They then proceeded to asked her to contact so called bank and the bank sent her a copy of the supposed contract from 3 years ago which conveniently expires February 28.

They ("fraud expert") then suggested for her to just pay the 2.5% penalty to pre-terminate the contract and save her BTC before the term expires. Because apparently her BTC will be sent back to her old wallet address that she has no access to if she doesn't.

What an elaborate scam. I advised her to stop talking to them and instead try to contact her old friend. I also tried looking to contact the bank but I'm also doubtful about the existence of the bank.

Has anyone here heard of Samoa Commercial Bank? or [crypto-guard.org](https://crypto-guard.org)?
