Kotak Mahindra Bank — Charged lien in my account without any reason

Address: Kakkanad

I have maintaining two consumer durable loan in kotak mahindra bank. Since 5th of nov was my first Emi date i have tranfered the emi amount to the account prior before the emi date. But emi not debited and i have paid the amount manually through the app. But after that day they have debited extra amount from my account. Today my friend transferred money to my kotak account, from that amount also they have charged money in the name of lien. disappointed with their service. I am not a loan defaulter. I have paid my loan within time. Then why are they charging money back to back from my account. Please resolve my issue and cancel the lien.
