Reliance Trends — offers displayed but the store is not giving it to customers

Address:

Door no 70/2 baar super market malancha road kharagpur, Munger, Bihar, 721304

I am a resident of kharagpur.. I came down for shopping at trends this evening and saw that offers is been displayed here that get 15% off on making payment through mobikwikwick. And 5%discount on sbi debit and credit cards but the store is not accepting any payments through these modes. If they are having problem then why don't they pull out all displayed promotions from store
Kindly assist
