I live in Nashik and use State Bank of Mysore. On January 7th, 2016, someone withdrew ₹45,000 from my account in Guwahati. My ATM card is with me here in Nashik. I want to file a complaint. Can you guide me on how to proceed?

You need to immediately inform State Bank of Mysore about the unauthorized transaction. File a written complaint with the branch where you maintain your account, mentioning the date, amount, and location of the unauthorized withdrawal. Also, report the incident to the local police and seek their assistance in investigating the matter.
