you have the easy solution but you stucked claiming a "scam": send them your 2015 tax return?

did and after that they refused to respond because they thought I don't pay tax so they blocked me

You answer only that?
you dont have an answer for this bro?

@OP are you able to give us references about 100BTC you claiming on that account?

It is important you give out the transaction id...i hope you realize it bro.
