ICICI Credit Card — Credit Card hacked and unauthorized transactions

Address:

Bangalore, Karnataka

I have a ICICI credit card and on 27th dec 2016 I received multiple transaction messages from bank that I have transacted with multiple merchants in USD, CAD, NZD and CLP. with in a minute I lost 30-35k. some transaction were declined and few were approved and lost 30-35k! I didnt receive OTP SMS. How can ICICI authenticate the transactions? I have raised a dispute and dispute # is SR[protected] . Also, I will be lodging FIR. Definitely there is a flaw in ICICI. If ICICI dont take this seriously then only thing I can do is to move to consumer forum. There is no mistake from my side. I have not shared my card details/OTP or anything and how can they use my card.
