Poor quality couches Fair Price Alberton

I bought a l Shape couch from Fair Price Alberton, couches delivered late at night, next day noticed the manager of the store and ask for WhatsApp pictures. Top L shape sponge was collected with poor quality and never got back. Now the arm rest is sagging and didnt send another video and no response. Im shocked by the poor quality of the coaches and regret why I bought the couch. They must just come collect it and give me refund for it.
