In January month statement I have seen one transaction on 16th Jan of Rs 4500 which I have not made and next day Rs 300 transaction charge is added. I have called customer care and informed the same they have blocked the card. I have not received any transaction alert via SMS or email. In that month my total amount due was Rs 13276.33 I have paid 8476.33 which I have used. I have mailed all the details to the senior management and they told to submit My Photo ID proof, Credit Card Copy and Police complaint, I have mailed my Photo ID proof and Credit Card Copy. They have given one address of ATM from where this transaction happened but this address is not traceable so no police station is taking complaint.
In the February moth statement they have charged Rs 4500 and Rs 584.93. Please help me regarding this matter.
