Illegal exchange rate

When I withdraw $850,
I received only ¥82,000.
The rate, USD/JPY, was 110 that time.
I told them to explain about exchange rate and fee many time, but they can’t explain much enough.

And when they change the swap rate,
They recalculated all of that.
I got swap point about $1,200 since few weeks, But it turned $200.

I have never trade such broker.
I won’t use this broker again.
