application bugging during trade caused losing all

Mu name is sofian Alzghoul, I've been an Investor in MTFE for two months account ID (1557908) Today on November 29th 14:40GMT I opened up a position in the application and due to the application bugging I lost all of the Trading margin that I opened up the deal with along with what I had in my net account value that I didn't enter the position with. I'm sad to report that after all the work and the profits and losses I had this was the worst since it was a SEVERE SLIPPAGE although I tried to close the deal before that happend more than two times (proofs in attachments) but due to the application bugging for about 3 minutes with the position open ,even the chart wasn't showing for me nor was there anychanges in the position as I was trying to close out on (700usd in loss). This bug didn't happen to ME ONLY ,I have 3 freinds that I know of who lost all investment over this bug too. The application has a stop lose mechanism that that didn't work too in a message with the support the said at 70% loss it should stop lose automatically although I had it at 30% manually , but instead the closing method for me was a BLOW OUT ,it even took what I had in my net account value with that one deal. Trading margin for this deal was 3163, and the rest of the fund was I started my investment journey with 3000USD had it up to about 4500USD and now my account is -10k which isn't logical and shouldn't happen if the stop loss had happened (proofs attached). I hope you mitigate this issue since the support team blamed this on market and investments risks and neglect the fact that the stop loss function didn't work and the application freezing in the middle of a transaction. I hereby appeal to a compensation since my loss was due to the application bugging in the middle of an opened position and even the automatic stop lose or the manual stop lose I had installed didn't work and lost the funds I used for the deal plus the funds I didn't use (had them in net account value).
