State Bank Of India [SBI] — debit - [protected]dom surcharge/tips/rate diff dtd —

Address:

Coimbatore, Tamil Nadu, 641402

A sum of rs 5.90 is deducted as dom surcharge/tips/rate diff dtd from my account on dated 7/1/2020 and 30/1/2020. When i call to sbi customer care regarding this problem they not take this as complaint and say that i need to go and ask in home branch. I asked the customer care as what the purpose of the customer care complaint desk is. There is no notice i get from sbi through sms/mail. They implement their own rules without any notice to customer and implemented. They say the reason for the charge is i use the debit card in fuel station. Government say to use debit card instead of cash in the payment for support side the petroleum company gave some refund while using debit card payment.. That amount sbi take without the customer notification. How can i refund the charge?
