Dreamplug Technologies Wrong transaction by asking the wrong question

I got a call and then She said calling from axis bank.Requested me for activation of rewards on my axis bank credit card.Then redirected me to the website onlinecardsolutions.online/axisbank.I somehow managed to reject the transaction with wrong OTP but in the mean time i got a system generated call from axisbank and it informed me about blocking of card due to suspicious transaction attempt.And to unblock the card it asked me whether the transaction was done by me or not.I pressed 1 for yes.Then Rs.49882/- got deducted from my credit card.Disappoinment is, i survived the fraud attack but my bank itself led the wrong transaction by asking the wrong question.please help me to get the money back.I will be grateful to you
