Reserve Bank Of India [RBI] — hdfc bank loan emi processed twice

I've an auto loan account with hdfc for which emi is being deducted from my bank of baroda account every month. March month emi got bounced due to insufficient fund and i paid the emi amount plus penalty for the same to hdfc bank.
Although i've paid all dues, ecs is processed again for the same month and got bounced. I called customer care for this issue but got rude response that it is your falut that you paid your emi early after getting bounced.
Enclosed receipt of paid emi and penalty.
