GCI TRADING SCAM CASE

I 'm sorry to say but GCI is nothing else than a big scam. I had an order with a SL at 20 pips distance and the platform exectuted that SL at 84 pips on eur/usd pair. I work with other three brokers and that is not happening even the volatility is very very high. The SL order is executed on time and at its value. I want to withdraw all my money from this scam and liquidate the account.
