Morestore — behavior of floor manager is very rude. not ready to exchange defective item

I have visited more Megastore Old madrass road and purchesed two Van Heusen trousers with Rs. 1199 with bill 2040-[protected]. One trouser which I purchesed was having fitting issue. Hence I visited store and I was asked to spoke Floor Manger( Saleem) to exchange the trouser with a uper size 32 size. At first he said you have to exchange both the trouser as you have taken offer of two. I said ok no problem, I will exchange both with other two. Then he said no it can not be exchanged as you have taken in discounted offer. I asked him where it is written that discount item will not replaced. I go through Term and condition which is written on back side of the bill, its writen if item purchesed with End Of Session Sell then it can not be replaced. When I purchesed this item no where it was written that trouser is in End Of Session Sell. Hence finally he did not replace trouser.

The behavior of Floor Manager (Saleem) was very rude, please educate your manager to behave with customer properly. I clearly told him I am visiting this store since 6 years. Floor manager (Saleem) is arguing with me saying we have not force/push to sell you trouser. You have tested and purchese the item. Why we will exchange it. When there is a provison for exchange.
