State Bank Of India [SBI] — Unwanted debit in my Home loan account

Address:

Kamala nagar, Hyderabad

I have Home loan account in State bank of India ( Kamala nagar, Hyderabad)

On 27th August 2022, my home loan account has been credited by Rs. 14, 500.00 under the description "single sided repa-by sma rec".
I have paid my EMI every month without any delay, and paid all sorts of extra charges which they charge the customer. Now to my surprise this has happened.
I have even reached out to the branch manager, he made me stay in the bank for 1 hr and told "check in your YONO app it will say everything". Is this how they resolve customers query.

This transaction is not authorized.
Kindly revert the amount which has been debited from my savings account and credited to loan account.
