Vodafone India — Regarding fraudulent transaction done on my credit card

Address:	Bangalore, Karnataka, 560100
Website:	VODAFONE BILLDESK

Hi,
I have got a call from one person saying that he is a representative of ICICI bank and asked me to redeem the reward points which will be expired today.
For this purpose, he had asked me to confirm the credit card number.
Post that, he said I had 2070 points which are going to get expired by today and to redeem that I need to confirm the card number and card expiry date. He also mentioned that 70 points will be taken up as processing fee and balance 2000 points will be credited as INR 2000 back to account.
He said the reference number and the details will be sent to my registered mailing address and told my registered email address over phone.

While I was on call I also got an message for a transaction of Rs 70. At PAYU-www.o has been initiated with an OTP in it. Since I refused to convey the OTP, he said you can enter the details through IVR. I have entered incorrect OTP for almost 5 times. Though I have not yet entered the correct OTP, but still he had confirmed the OTP received on my mobile over phone. He even said that my credit limit can be increased and informed me that the credit limit can also be increased for my card for which he had done a transaction for Amount 20000 towards VODAFONE BILLDESK. When I questioned him for that he had replied saying that the amount is only for increase in credit limit and not any transaction. But I had got an SMS for the same amount 20000 INR towards VODAFONE BILL DESK on 29thMay at 16:12PM. Request you to consider this case and stop the payment processing to the VODAFONE BILLDESK from my credit card account.

He even said that his employee name is Praveen Choudary and employee ID is 28913. Mobile from which I had received the call: +91 [protected] (Praveen Choudary) and +91 [protected] (Manish who had called first later scheduled the call with Praveen)

Below are the transaction details:
