Groww — Dashboard is not updating, lost all money in the trade

I did a FNO trade, and it was not updated in the dashboard
I was not able to put the trade to sell.
It took me 10 min to connect on the ph and they said backend team will take care of this
All my money in that trade went to zero in front of and I was not able to do anything just because of groww's incompetence and lack of technical expertise
I demanded to talk to a senior associate and refund of my money, not only they straight away said no and told me you can raise it at any place but we will not refund and even charged for the brokerage as well
It took me 4 days to connect with their senior associate that too when i called them regularly
