I see two choices.
1. Give them a choice to waive ALL per-trade and monthly fees until the account goes positive. Let them know that even if they agree to this, any drawdown of more than 10% on the current balance should be dealt with by immediately closing all positions and not trading further without your authorization.
2. Close the account. File complaints with anyone they are registered with. Unfortunately, if this was just incompetence rather than scam, there's not much anyone can do about it. Incompetence doesn't violate any regulations, but you might be able to make a case for gross negligence. You would need to consult a lawyer familiar with forex issues for this.
If they really think they have a serious chance to bring your account back, they should happily agree to #1. Something tells me they won't.
