huge scam broker alert

Hi there
I just would like to lay a complain against this broker fbs , reason why , I was in profit and I decided I wanted to close the trade and as I closed the trade I get a invalid error message and all of the sudden I see my account is completely wipe out !!! I don't understand what they did because I was in profit and then just as I wanted to close the trade the whole account is wiped , Someone please look into this matter I am more than happy to provide you with the account details , I am beginning to think that this broker stole my money and that they might be a huge scam.

Thanks in advance
