Bajaj Finserv — unnecessary deduction of amount

There is no reason why there has been this deduction out of my savings account. This is a very difficult situation for me and every rupee is very important. I had only 600 in my account. How can you guys take all the money from the savings account without any notice. This is unlawful. I had a words with icici, they said this is done by bajaj. Please check and refund my money.
All the emi has paid on time.
Pls refund the amount.
