On 10th August I swip my SBI debit card in HDFC Bank ATM (Madhyamgram branch) and due to connection failure the transaction was failed and no slip came out from ATM machine. But 12Aug when update my passbook I see 2000/- was debited from my account on 10th Aug transaction which is unauthorised.
Please check it properly and credit the above mention amount in my account.
