It is not unusual for brokers to be wary of immediate withdrawal requests even when no trading has taken place. One could even say especially when no trading has taken place. They are obliged by the regulators to avoid any transactions that could be part of money laundering operations, even on a small scale.
I suggest you talk to them on the phone and confirm by e-mail and refer the matter to their regulators if nothing happens. I am not sure who this company is regulated by, but it seems to be an Estonian based firm? I.e. in the EU. But it does not seem to be complying with the ESMA rules concerning information required on their website.
I do not understand why you would have deposited your mortgage money into a trading account!!! Did you really expect to be earning another $1000 from your trades before your mortgage payment became due? How did you intend paying your mortgage if you had not changed your mind about this broker???
First rule of trading: NEVER, EVER, risk money you cannot afford to lose - however safe you broker is!
Good luck of getting your funds back!
