It does look that way, although these things are never simple.
Banks are regulated and have processes in place but if a customer is scammed there's sometimes nothing the bank can do (this is my line of work).
It really is terrible but fraudsters are clued up and figure out new ways to con people every day. Good luck to Hamilton in recouping the funds but it may not be easy.
I'd advise anyone to contact their bank themselves if they are ever asked for their details or to transfer funds. Always double check - some very clued up people have been conned, so you're only taking necessary precautions.
