A ******* store that sells faulty items

I bought a fluffy white ottoman end of June cash, obviously threw the slip away, no one sits in a house full of slips honestly. The product is now damaged , the zipper came out of track and one can see the item was handled with care and damage is not due to mishandling, the item is faulty. This was R1000 and they now telling me I can’t exchange cause they want the slip. Where am I gonna get the slip , this item is still a new item in their stock and it’s faulty!
