Very bad slippage!

My position and the money that I deposited was blown to dust! There was some serious slippage that happened! They purposely liquidated my position to take my money away from me! If it was due to Major News Event, I would've not made any complaint. Only this Broker's price chart were being Dipped during the slippage happened! I did set my Stop Loss and Take Profit, but still my position were wiped out. It seems like I’m not the only that is facing this issue, I saw many more people regarding the same issue. I went ahead and asked Customer Service on what happened, they claimed that it is Liquidity Provider's Fault. And they send me an email. I asked two of the Broker's LP, they claimed that they have never work or cooperate with the Broker involved.
