State Bank Of India [SBI] — wrong charges deducted

Address: 322230

Today i got a message from sbi stating that your account is debited with rs 2400 debit by transfer.
I immediately checked on netbanking statement it shows debit by transfer rs 2400 on 08.05.2018 though i got message on 16.05.2018
My account balance was below 2400 on 08.05.2018 and i have done no transaction of Any type on said that.
I complaint regarding this on sbi phone banking support they registered my complaint and got the replay from branch that this deduction is according to existing terms and conditions please check online on sbi website about services charges.
I checked about it there is no such charges.
My sbi home branch employees are very bad they never pick the call and doesn't behave decently if visit the branch
Currently i live out of town so i cannot visit the branch personally and i have to again complain about it but no result.
Please provide resolution
