Bank of India - Insurance Policy Issued Without Consent Home Loan BOI

I have a home loan account at Bank of India Bangur Avenue Branch in Kolkata, West Bengal (Loan account no- ***************). When I borrowed my home loan it was said that property insurance is mandatory for * year. Hence I requested to do the same for *st year only. Also during my loan processing, I gave consent over email (to the loan processing center) that I do not require any kind of insurance of my own. So as per my request, my *st property insurance premium was deducted last year, which should not be extended any further. But yesterday I got an SMS from Bank of India that Rs. *****.** has been deducted from my account for insurance premium again!!

How can the branch deduct my money without my consent? I haven't opted for any property insurance from *nd year onwards. Yesterday I called the branch manager on this number: ***-********, but someone else picked up the call and did not forward the call to the branch manager. I immediately need the full refund of that amount (Rs. *****.**).

Additional Note:
It has been a very pathetic banking experience with this bank. I need a proper resolution for all of the mentioned issues as soon as possible, please!
*. Previously they deducted a huge amount as interest on my home loan just because of their own mistake (during lockdown period). I emailed several times to head office, branch and zonal email ids to get the refund but no one replied.
*. Also for my previous property insurance premium (which I had paid last year), they did not provide me with any policy document for that.
*. Now they have extended that policy without my permission. Continuously I'm having financial loss with this bank and no one bothers to help from their end.
