Consumer Redressal

I am a Citibank Indian Oil Credit Card holder and my card number is 5546379689689014(old) & 5546370227930911(new). On 18.03.2015 at 10.59 AM I received an SMS from VM - Citibk that I had spent Rs.5,040.00/- on my Credit Card 5546XXXXXXXX9014 at AIRTEL PAYMENT. But before this SMS I received a Phone Call on 18.03.2015 from Citibank Customer Care (09350745278) at 10.42 AM. Whereas I have not done any transaction at "AIRTEL PAYMENT" at that time. I was at my home. I immediately called Citibank Customer Care and blocked my credit card ( 5546379689689014) and complained about the 'fraudulent transaction' which took place. The customer care executive told me that the old credit card has been blocked & the new one has been issued. Moreover she told me that I will have to call Citibank Customer Care again on 23.03.2015 for logging the complain about the 'fraudulent transaction'. She also told me that I cannot log the complain at that point of time as the "system" would not accept it.
