It has been over 7 months now and they do not reply to my emails and my funds are still locked

As it is a long time but you haven't got any response from them you should re-email them with as many details as you have and wait for the response from them. Please don't spam if you spam then they will ignore and if they ignore then your message will be turned into spam and if it turned into spam then you will have no chance to get any response from them.
