Poor customer care

I bought a couch last year December at Lephalale store, when they delivered it they scratched it at the back and when you sit on it, it makes funny noise. I reported it they sent someone to come and inspect and told me they logged a complain so I have to wait. After a month I called the costumer care only to find out no complain was logged. They logged the complain and promised to resolve the matter. I have been calling the store manager and customer care with no luck.excuse after excuse. The store manager then told me I have been approved a new couch which they will deliver later that day Till today am still waiting for the delivery. When I call the store manager she’s always busy or promised to get back to me
