Canara Bank — complaining against a fraud transaction of rupees 40, 000 made from my account

Address:

Canara Bank, Neelam Place, khoja Imli, Anisabaad, Patna, Bihar

On 14 th of july 2020 at around 9 pm i received a message that 40000 rupees is deducted form my account in an atm transaction made in lodhi nagar patna bihar. Which seemed impossible as my atm card was with me i received no opt or call on my phone number regarding the transaction. I immediately got my card blocked by texing "suspect" and by calling canara bank costumer care. Wantthe following night i reported it to the police station and the next day i also registered a complain to the canara bank. Since i did not received any otp or call before the transaction was made i want the bank to look into this matter and help me though out the process.
