I tried to add credits from my zerodha trading account which had a balance of Rs.3000. While adding credits of Rs.2000 for the first time, due to some technical glitches my developer account billing didn't show any response at the first. So I selected add credits again. Later I came to know that Rs.2000 where debited from my zerodha trading account twice and now it have a negative balance of (-)Rs.1000. Also I used 2000 credits for subscribing to kite connect and my account is still having 2000 credits. Is there any way through which I can transfer back this 2000 credits back to my zerodha trading account and even out my balance.
