State Bank Of India — Two transactions debited from my account without my knowlede

Address:

Kolkata, West Bengal

To whom it may concern, When I was booking my TOEFL exam on 23 rd May, 2015 I tried to pay with my SBI Visa Card and I logged in two times through the OTP which came to my phone. But in both the times a message came "Dear customer, your transaction at POS 00000001 declined due to authentication failure. Please try after some time." But today after 2 days, when I took out a mini statement at my nearest ATM, it showed two transactions of the same amount of Rs11042.90 being debitedon 23.5.15 at "POS PRCH". This is a very serious problem and the amount is also very large. I want the amount to be refunded. Please help me out by throwing some light.
