SBI — Charging customers heavily without information

Address:	SBI, MIDC Hinjewadi branch, Near Hinjewadi chowk.
Website:	retail.onlinesbi.com

I had to deposit cash in Hinjewadi SBI branch and so waited in queue for some time for bank to open and when I was entering inside the security guard there told me they don't accept cash deposit inside the bank now and need to deposit in the opposite Customer Service Center. So I deposited in this center and next day I saw the in the account that Rs. 84 is deducted from my account for depositing cash through customer service center.
Why this bank does not inform prior for such charges ?
I want refund of this charges.
