Exness Broker Manipulating trades to make trades blow their accounts..

I have been trading with Exness and I had disturbing encounters using their platform. I placed a sell order on GBPUSD & it will be deeper in loss when the sell candle stick pull down.then when buy pulls up it gets in profit.I tried reaching out to them but no response.I have recorded the live trades of my accusations and sent it to them. Exness is manipulating trades and it does this to many traders who are not aware!!!
