Poor service delivery - wrong carpet supp****.

I ordered a carpet for R270. Your website shows item is in stock. When the carpet arrived, it was the wrong style and colour. I logged a return with the preferred outcome of replace the item with the correct item. Now YOU changed the preferred outcome to "credit my account". I don't want my account credited coz then I have to order all over again, pay more for the same item AND pay for delivery! Please replace my carpet with the correct carpet ordered since your site clearly states it's in stock! My reference is MRRN-P5ZQM-BYG7.
