Citibank — fraudulent transaction in the name of fb ads in citi credit card

Address:

Chennai, Tamil Nadu, 411057

Hi,
There are multiple fradulent transactions of about 7 at the same time of total 12500rs deducted from my citi rewards credit card.
I dont know how it happend as i have never used my card anywhere in fb.
I called customer care and they are telling its international transaction which no need of Authorization.
They wil raise a dispute and team wil investigate on that in 90 days.
Its really worst case which ever happend till now with other banks.

We use banks for storing money safely and if it happens how we keep trust aymore.
Im always ready to fight on this:[protected]
