Reserve Bank Of India [RBI] — Other

I have purchased diesel for rs. 1, 000/- from sri sati service station, raxaul (Bihar) on 16 dec 16 by swiping my debit card. An amount for rs. 1, 028.09/- has been debited from my boi bank account [protected]. I am unable to make out why this an additional rs. For rs. 28.09/- has been debit whereas govt of india is insisting and promoting the cashless transaction and an aid is giving for such transactions. Whether this amount should be refunded or not? The transaction id to this effect is 49028612 between boi and hdfc bank dated 16 dec 16.
