No refund policy

I bought a Pineware iron on the 12/04/2022 and on the 13/05/2022 it wouldn't switch on. I took it back to Pick n Pay Wonderpark and, the guy [Jabu] tested it on more than 2 plugs. He even went to the back to test it. Worst off, he took his time whilst doing this. When he came back confirming that the iron was no longer working then another lady came with a replacement iron. I didn't want another iron, I wanted a refund, but I was told that it's company policy that I get a replacement and it's either I take the same one or I can add on to get the replacement iron I want.

Why am I being forced to take something I don't want?

Whilst I was there, a staff member returned a Pineware 2 plate stove because it was faulty. I didn't want another pineware, but I want the freedom to purchase another iron wherever I want.
