Citi Bank — citi bank credit card fraud transaction

Address:

Bangalore, Karnataka

My name is Munavvar Parvez. I am using the Citibank credit card from March 2014. On 2nd June 2015 two fraud transaction has been happened with my card from US. The amount of fraud transaction is in USD which is 1033.00 USD and 6.00 USD. I have complained about this fraud transaction to the Citibank Just after getting alert message and informed to Citibank that this transaction was not made by me and have asked them to block my card. The bank authority have not taken any complaint but have asked me to wait for 3 days till the merchandise claim the amount. Now I'm not sure If I have to raise a complaint against cyber crime. I have read a lot of complaints against CITI bank where users have faced similar issues and after few months citi bank have been asked to pay the amount stating "they have done their investigation and they found that the transaction was done with valid IPIN and said that one have to pay the transacted amount" .It's been 7 hours since I reported the incident but I would want you to know well in advance on this case and if possible stop that transaction and suggest me what to do next.
