No Discount On Damaged Dress

Im am very disappointed with Forever New SA Gateway branch.I bought an item online,unfortunately it didnt fit me as expected.I went to do an exchange however was not available in store so I decided to buy a dress.Whilst I was fitting the dress I saw that it was damaged.I went to the till to report the damage and I told them that I will still buy the dressed even thou it is damaged because my size was no longer available.I expectec them to be very lineant as the dress was damaged.Maybe a little bit of discount.They refused,they will sell it to me with the normal price.How disappointing.
