Severe slippage

Participated for a month and a half, and invested more than 10,000 US dollars. I encountered many smashed orders and set a stop loss. The platform was unstable and directly exceeded the stop loss point. The analyst explained that the smashing speed was too fast, so the loss value is burden by the customer? Is this platform so unstable? At present, there is only 2,000 US dollars left, and there is no point in operating it.
