State Bank Of India [SBI] — deduction of money in my personal account

Address:

Chennai, Tamil Nadu, 600036

A total of rs 26.97 is deducted as [protected]int surcharge/tips/rate diff dtd from my account. What is the plus point of going cashless when bank can deduct some amount after the transaction is done? Nowhere it is mention that a certain amount will be deducted from account if you pay using the card so that consumer can prevent from doing so. It's like cheating consumer to pay for using the card and then, later on, deduct some amount from there account without giving any notice or proper information why a certain amount is deducted.
