I am an account holder of Punjab National bank in Kerala. The bank has issued an ATM card and I used the card at Dubai airport and some ATM machines in India also. After some time an amount of Rs 110,000 were with drawn from this acoount different days without my knowledge or consent using ATMs abroad. As these transactios happened, I was abroad. On noticing the money theft, immediately notified the bank and a written complaint was made. However five months have been passed since the bank did not send me a reply on my complaint nor compensate my loss. I have complained to the GM customer care but they say they are not responsible for ATM fraud and directed me to Banking transaction division. The banking transaction division is least bothered to reply me. How do I sue the bank ?or is there any legal base for my case as per Indian law?
