HDFC Bank — Not get discount as promised

Address:

Panipat, Haryana

Dear Sir/Madam, As per promotional email by HDFC bank, that If i pay my BIgbazar bill of more than 2000/- by HDFC debit card on Wednesday i would get 5 percent discount . I went to shopping on Wednesday i.e. 29/07/2015 in BigBazar keeping in my mind that I'll get 5% discount if I pay by HDFC debit card as advertised by company. I shopped in Big Bazar Panipat for 3457.50, Invoice no. 1236007 Tr: 53908, paid by my wife HDFC debit card no [protected] for 3458/- INR but I was suprised i didnt get said discount although i have fulfilled all requirement. After inquiring i was told by Big Bazar guys that that is bank problem sometime card didnt show discount . So was this a fraud ? I felt cheated . Kindly look into matter. Yours truly Dr. Mohd Imran [protected]
