Flipkart — Unauthorised transaction has happened in my flipkart account through my hdfc bank credit card

Dear sir
On 17-5-23 at 8.15 am some unknown transaction happened from my HDFC Bank credit card through my Flipkart account. Somebody hacked my Flipkart account and purchased some non-refundable gift cards through my credit card. By mistake, I saved my credit card in the Flipkart account for future transactions (only my card no). the morning I got one call from an internet number and from the other end there was no response but I can hear somebody staying at the other end of the call suddenly some messages came to my phone that to OTP request and next some messages came from Flipkart side that some this has been purchased and delivered successfully the same type of messages came two more times suddenly I realized that my account is hacked I call bank customer care for blocking my card and raise a complaint against and even I contacted Flipkart for the same and there also I have registered a complaint.Since[protected] I was waiting for my complaint confirmation but there was no response from Flipkart's customer care side. Again I contacted Flipkart customer care and they told me that Flipkart's confirmation of my complaint and its rectification details has been mailed to my email. Still, I have not received any mail from Flipkart from that day[protected] onwards. again I contacted customer care regarding not getting any mail.Each time when I was contacting the backup team regarding the above issue at that time they say the date that my issue will rectify. From[protected] onwards I have got 3 dates still now no rectification happen. On[protected] I clearly informed the customer care support team that kindly cancel those gift cards or else stop the gift card to be used anywhere else because as per the information, it is an online gift card. Now my Flipkart account has been blacklisted or blocked by Flipkart because of that I am not able to access any updates regarding those fraud orders placed. even I am not able to see the mail id registered with my Flipkart account. by considering above mentioned details kindly help me to cancel those unauthorized purchases that happens on[protected] and refund back my money as early as possible
