My mistake yesterday, I sent my Bitcoin to Bitcoin cash. I didn’t realize until it never posted.

I was withdrawing from Brittrex over to Polonienx. 

I’ve tried contacting both of them via support help, but no response.

Will they help, does anyone have advice or know how to fix this.

I had over $5000.00 in that account.

Why do they allow that to happen, when it’s not correct?

Why isn’t there an error message saying you can’t transfer unless it’s bitcoin to bitcoin?
