Broken Furniture - not even 6 months old!!!!

I'm disgusted with this company - I would really think twice before buying from them in the future. I bought 2 lounge suites on May 2022, now 4 months later, the unit L-Shape suite's one coach broke while just sitting on it. Trying to get through to customer care is a total waste of time, until reaching out to the CEO. Now they want to repair the furniture, which I'm not accepting as it's new furniture. I demand a replacement.

If I buy a microwave at GAME and 4 months later it breaks, they will replace it because it's under warranty - What makes this business so different. If I don't get joy my next port of call is the Consumer Goods and Services Ombud as well as the National Consumer Commission.
