On Dated 9/08/2017, On 17:16, Suddenly,I got lot of SMS on my mobile about Heavy Transaction from my SBI credit card. Also I got SMS that my credit card is blocked due to suspicious activity. After automatic blocking of the card also, there are lot of massages of declined transactions. 

All transaction were in US Dollars and other foreign currency and the amount of some transactions were very high even very much higher than the credit limit of the card.

Then I have contacted SBI credit card customer service representative and told her the case and requested to block the card permanently.
