Disappointed defective genuine leather couches - CORICRAFT

I bought 2 couches from coricaft, one in Cresta and the other one in mall of the South Johannesburg , both were delivered in Rustenburg as it is closer to where I reside. The couches didn't even last a week I saw cracks developing, I called the Rustenburg branch in May the 26/ 27 as it is closer. i wanted to know when I can return their couches as I cannot use defective furniture. i made an appointment with them as I was travelling to Johannesburg. I gave them pictures which were forwarded to the manager, note there is a what app portal that I used which doesn't respond . Guess what they want 10% of the total amount if I return the couches or I can choose the other fabric and pay the difference. My question: 1. If you sell genuine leather why does it crack? 2. Why must I pay 10% of the total amount of couches when coricraft sold me defective couches? 3. Are they complying with National Credit Act ? 4. How long will it take for Coricraft to respond? Should have read the reviews, Coricraft is the worst furniture store ever, their business etiquette is disappointing. Now their head office is giving me the run around - time wasting, they want information they have on the system from me.

I AM DISSAPOINTED
