It's quite opposite for me, my @kotak is working and @kotak811 is having an issue because till now I have tried to do 2 transaction and both the transaction failed and yesterday when I did the transaction the money got debited from the account but they weren't received at the other end. I raised the issue about it and they said it will take T+1 day to refund the amount and today morning I also got the call from kotak that my money will be refunded by tomorrow morning. So I think only one of them will work. After I get the refund I will check everytime with a small amount before trying because if it fails then the money will be stuck for 2 days.
