Bajaj Finserv — payment issues

Address:

I had kept funds in my account for bajaj emi but it didn't get deducted on that day accepted but after that when i paid it manually it didn't get any update in that and so i have to pay the amount again with getting bouncing charges on top of it also my cibil score got affected so kindly update my cibil as i didn't bounce any of their emi.
I need an explanation on that why my ECS didn't cut on time even though it didn't they should have texted me something like that and it was very first EMI of mine and got bounced it hurted me
