In my Flipkart Account, someone ordered 15 gift cards with my credit card payment. How they are getting OTP? I don't know .

Suggest me a correct solution

Rush to your nearby police station and file an FIR. Then file a case at the cyber cell by including the FIR number. Also, approach your bank(who issued the credit card) and ask them to block the card ASAP.

Lastly, call Flipkart customer care and let them know the issue as well.

First block your credit card and Mobile number.

Block ur credit card and contact with ur bank within 3 days but I don't know if ur amount refunded or not
And as soon as possible reset ur phone
