State Bank Of India [SBI] — excess dr in sb

Address: Patna, Bihar, 800025

My bank account which is in SBI Ashiana Nagar Patna has deducted INR 944 on 07/06/2018. I don't know for what it has deducted because the last transaction is on 05/06/2018. Because a man transfer INR 500 on 05/06/2018 on my SBI account . I'm totally fed up with this bank... because initially also it has deducted approximately INR 300 for not maintaining minimum balance
