Bajaj Finserv — ECS bounce though sufficient funds available in bank account

Address:

Bangalore, Karnataka, 560060

I'm a customer of Bajaj Finserv with loan a/c: 4040CD34197891
I have another loan a/c from them which had no issue of bounce in ECS Payment till now.
But today 02 Feb 2017, the ECS has payment is cancelled for loan a/c said above which is supposed to be the first EMI payment. My savings account from which ECS had to be deducted had sufficient balance for the automatic payment yet the ECS was cancelled.
I don't know why, because this is the first time it happened with me.
Bajaj Finserv executives, please do solve the issue since there is no problem or errors from my side.
