[Resolved]  HDFC Bank — credit card fraud

Address:

Faridabad, Haryana, 121009

Dear Sir or Madam:

I am writing to dispute Credit Card fraudulent.[protected]:15:14:35)
I got a call from HDFC backend office. Person told his name Rahul. The number was a cell number ([protected] & [protected]) from Delhi. But the modus operandi was similar. They tell me about my bank document detail (DOB, PAN No, Account no, Registered mob no etc...)exactly and told me that I am using my credit card reliably for a long time so I have been eligible for HDFC Regalia credit Card.
Next day this guy call me again and told me, kindly pay your outstanding amount then you will eligible for applying a Regalia card.
And I did pay my total outstanding amount; then this guy asking details of CIBIL score and over transaction limit of my credit card so that they will check my eligible limit.
That guy constantly online with me on the phone

After few minutes later I received a message on my registered mobile number
OTP is 439859 for IVR/Online
Trxn on your HDFC Bank Card 3308
and valid till 15:23 hrs. Do not share
this OTP to anyone for security reasons.

After few seconds I received a message again

Dear Customer, Thank
You for the registration/Password
Reset attempt made on your
HDFC Bank card for 3D secure authentication.
Please complete the process and
Enjoy secure online shopping with
Enhanced security.

After few minutes I received a message again
Rs.26079.00 was spent on your
HDFC credit card ending 3308 on
[protected]:15:14:35 at AMAZON.
Avl bal- Rs. -1053.65, curr o/s
– Rs.26053.65

My total credit limit is 25000 and I got the debit of Rs. 26, 079/- (Rs.1079 is over from limit)

I called up the customer care (HDFC Bank) and blocked my card and I have been told that the payment will be stopped. I am surprised that how the amount was debited from my credit card without the OTP or secure pin.
I tried to know this transaction detail from amazon.in customer services but he said that; please provide the transaction ID. I tried to get the transaction ID/information from HDFC customer executive. But no one provide me the transaction detail.
Please look into it seriously.
