Return

I bought A5 Lino sheets x 5 at PNA Mall of Africa and we only used 2 sheets and I went to PNA Raslouw Centurion to return what was not used only to be told I must return them at the store I bought them from, It's the first I have heard of such. If I am from Limpopo and bought a product in Gauteng, I must drive all the way back to return it. The manager was not even interested, and he said this with a straight face and nowhere in the receipt and upon purchasing this was mentioned.
