Hi, i also received the same job opportunity in UK with Flyff Training & Review Center. However i haven't called to their office yet, i am also doubtful with the job because when I e-mailed my resume using my jobstreet account I am not applying literaly for UK. 
I feel scam for the "3800 payment".. 
pls guys update me about your investigation because I am far from manila. It will be a waste of money if I personally go there to find answers.  Lets help each other.. Tnx
