Less than 1 year old Dining room suite and I must pay for repairs due to poor quality?

I purchased a Dining Room Suite almost a year ago. Within a year, the cushions have collapsed and I have had the displeasure of having to seek support from the JD Group for remediation. Suffice to say, the eventually collected a few of the chairs - now 5 weeks later, I have not received feedback nor status on the exchange or repair. On calling the contact centre, they advised me that the item is in the warehouse - awaiting quote approval for repairs? Quote approval for repairs on poor quality item that didn't last a year, and I spent R20 000 on....are you for real? Please rather come collect your poor quality merchandise and give me my money back
