[Resolved]  Reliance Digital — not allowed promotional discount coupon benefit

I purchased a mobile for rs.13999/- on 25.11.2017 and at that time i was given a discount coupon of rs.699.95 which can be utilized by 31.01.2018. Today i visited your reliance digital showroom, in sahakar nagar to purchase a iron box costing rs.969/-. But your representative (Mr ramanadhan) has informed i am not eligible for discount as i have to purchase for rs.1400/ (Double of discount amount)
But i was not informed the same at the time of giving the discount coupon on 25.11.2017. I felt that if the same is reflected in the discount coupon, i would have planned, but suddenly now they have informed that i am not eligible for discount coupon unless i purchase for rs.1400/-.
I request you to kindly allow me the full value of discount coupon, as i am deprived for non passing on information by your representative at the time of purchase.
