Bad experience

So I bought a tent on Tuesday 2 March 2021. That same day I went to visit my grand mother as it was her birthday. I was so excited about this tent I told my uncle and he said no but its too expensive. He said game have better deals and I could borrow his tent for my camp till I get this deal.

So I decided to take back my tent to shoprite. I didn't even take it out of my car. Coz Im not gona open it.

On the 5th March 2020 which is today, I take my tent back to get a refund. The customer service lady said she need to check it first.

So when she checked it it appears to be used. So now I can't get my money back as it was used before.

Firstly I told them I did not use this tent. So this means that I naught a tent that was used before from their shelves that has been used for full price.?

Why did they not check the tent before I left their store when I bought it? But as they so eagerly want 2 check it when I bring it back.

Now it seems as I am a lier and a cheat??

This I found very humiliating.
