Indusind Bank — unauthorised use of my credit card

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201306

I, kumuda chandra pradhan using induslnd credit card ([protected]), yesterday night at 11.22 pm, rs 30000/- debited from my credit card without any information. After first deduction i immediately called to customer care at 11.26 pm to block my card but my credit card was not blocked by customer care and, they have tried to debit 30000 again but it was not successful and again debited amount of 10000/- twice from my account.
Total rs 50000/- has been deducted from my credit card and there was no confirmation asked me like otp. This seems to be very serious security concern as i had taken your bank card and could not find security of my money.
As per received messages i found that amount may be transferred in a wallet of [protected] and also used some amount for paying of mobile bills. (All reference are enclosed)
It is request to please investigate this matter and get the amount back in my credit card and till then kindly block my card until i give you confirmation in written at your branch office.
