Canara Bank — money deducted from account but not received them from atm

I have my account at bank of baroda manjalpur branch with account number [protected]. I had used my atm card to withdraw money from iit gandhinagar atm on 24th august 2017. The amount of 1800+1800+1700 was deducted from account though i didnt get any cash from atm. Let me know how to get refund of the above. My name is rutu patel and email id is [protected]@yahoo.com.
