Canara Bank — Illegal Transaction

I had lost a sum of 4500 from my Canara bank account through an illegal transaction without my consent
I had approached the Police and filed a F.I.R regarding this and they told that the bank should refund the amount
I approached the bank and the customer service and both of them denied service
I would request you to do the needful and dispute the lost amount

I’ve asked other people and they got their disputes without approaching the cops About it
Please do the needful
