Well I've reviewed both of your snapshots and it is clear that your enormous 150 long position on EUR/CHF demolished all your deposit, triggered stop out and drive your account into negative balance. Doubt you could overlook that and your complaint looks like a unavailing attempt of money extortion . I truly understand your disappointment and how you fret and fume because of colossal loss, but it is ridiculous to take out the fault of Hotforex from the thin air. Sure you are a mature trader and able to take it on the chin.
Best of luck!
