Groww — Orders not executed in time

Website: groww.in

While trading Banknifty 37500pe around 9:30 today, my exit order wasn't executed. In fact I had placed exit order twice, once at 480cmp and again around 460cmp (selling at market). Both the order were cancelled after about 5-6 minutes each and no new orders could be placed meanwhile. Those 10-12 minutes were really distressing.

I wonder if Groww can't render their services we'll, which broker would. Pathetic experience today. Had incurred a loss overall. I should have been able to exit the trade whenever I had to, it shouldn't be at GROWW's discretion when to exit a trade. If I wanted to exit at 562cmp, i shouldn't have had to wait till cmp was down to 490 and again had to place an exit order for 500cmp.this time too it didn't get executed until much later. Very disappointed and shocked by groww's service standard.
