Name - gopal krishna majumder, he had tried to withdraw rupees total 30000/- from ubi and sbi bank atm machine in howrah shibpur -711102 on 1st april 2019 morning. However money has been debited from allahbaad bank account but he has not received cash from that atm machine and showing "system error, please contact with bank". Till today money hasn't been credited back into his allahabad bank please registered my complaint and please credit back the money. I have multiple times tried to contact with customer service mentioned at the back of the atm card, but noone was picking up my call. I have dropped mail too but didn't get any response.
Please treat this as an urgent basis and refund his money back.
