After filling the details, my credit card for charged with 81240. I immediately informed the bank about the fraud. I also informed flipkart where the transaction was done. I also registered complaint on cyber cell 1930. Inspite of all this icici bank charges my credit card on 18 april 2025 and told me to pay the amount.
