Bank Of Baroda — international transaction through closed credit card

I had closed my bank account associated with my credit card and also my card. After which bob stopped sending me any e-statements of my card, which was the indication that it was not active. After a few months bank approved an international transaction on my inactive credit card. After performing this transaction bank did not care about informing me immediately. I was informed about this transaction after 3 months with added late fees. Now i am constantly sending emails to bank authorities to block my card but have not listened from them.
