State Bank of India — regarding extra 4 % charge asked by the merchant on payment by debit card

Address:

Kamrup Metropolitan, Assam

Recently i went to purchase a laptop, but when i went on to pay by card he asked me for 4% extra charge. I know it is not legal for the merchant to asked for extra charge. So as a responsible citizen i want you to look into this matter and teach a good lesson to this merchant.. thanking you, contact details of merchant:: Innovation Paltanbazaar Guwahati +(91)-[protected]
