Mobikwik — fraudulent call

On 6-9-2019 i received a call from a no. Saying that they are calling from axis bank credit card service. And asked about credit card queries. I refuse to gave the details. But they said that I can increase my card limit thru online. They have furnished the following details. Card number, name, email. Due to that I have provided the otp.
The amount debited in 2 transaction such as 24999 and 25999 from my account. Total 50998 rupees debited.

"this amount debited to mobikwik account"
I gave him card no., name and cvv, i was not knowing anything so i gave him the otp for all transaction... Then my account is debited with total 50998. This transaction was not done by myself. So please raise this issue and resolve.
Thank you.
