[Resolved]  Bajaj Finserv Loan — Unauthorized credit card charges

Address:	500010
Website:	www.bajajfinservloan.com

I had made a transaction of amount 20, 671 for purchasing an a/c from the website https://www.bajajfinservloan.com on 9th april, 2017 between 8 to 8:30pm with my hdfc credit card. I got this website link from olx from unknown user (Who is is from noida). When i made the transaction, received a call from a person (Mentioned his name as pramod) saying he is from bajaj finserv and asked about the product details which i was trying to purchase.
When i was attempting to purchase the product, the transaction was pending. So this person had made some changes for the website then i received otp to my mobile. This person asked the otp to make the trasaction success. This person made me believe in such a way that i had to give otp and he made the transaction success and informed the product will reach in 4days.
He also asked to check the website as the order was success and order status was laso ready to pickup, waiting for courier.. Blah blah..
Now the site is not at all opening too.
I had waited for the product for 1week.. Tried to cal the person from which i received the call. Its switched off. Then i realized i had been cheated. This transaction was made to some www.justdial.com, gurgaon
I had made several complalints to hdfc customer care.. They had reverted the amount for 1month and again they had charged me for the same transaction mentioning that "merchant has already provided the services to customer".

Please help me and provide the refund of that amount.
