I had gone at, reliance fresh S.G.MALL, THALTEJ AHMEDABAD, to purchase 15 lt. jar of sunflower oil, i selected" sunrich sunflower oil " price displayed was Rs. 1149/- After waiting in queue for 10 mins., counter girl after scaning asked for rs.1199/-, So i told to check the price displayed, ultimately after 10 minutes I called Manager . Now he bluntly told me that today's price is 1199/- !!! He not even shown any regret for this mistake but keep going other side without attending me! Is this CUSTOMER SERVICE ?
