[Resolved]  Amtec Engineers — Credit card fraud

Hello Sir/Madam, I got a call from[protected] and[protected] yesterday regarding redeeming my reward points. They were able to tell my due date and last transaction. Also, they sent OTP from AM-ICICIB, that's where i thought they were genuine and shared my credit card details. They have made a transaction of 6999 against my credit card for amtec engineers. Today when I called customer care i got to know it is a fraud call. Please help me in cancelling this transaction. Also, please look into this case as it looks to be a security breach and it shouldn't affect other customers as well. Thanks, Dhana Lakshmi
