Bajaj Finance — Cmp mandate July 21

One week back, I got an SMS from the bank (Your a/c has a debit by transfer of rs.117/-on 12th July 2021). We brought a A/C and LED on EMI in 2016 and it deducts from my account, with no due we paid the whole amount. And then why such a deduction? I didn't know what for this. How can you deduct money from our account without any notification, yeah we give our whole bank details to you which doesn't mean that you can make money from that whenever you want. So I want a refund of the amount 117 or I will go for the further procedure. Even the EMI tenure, is finished you are not allowed to take money from my account.

I want the deducted money in my account as soon as possible .
