Paid for Damaged Goods and Terrible Service

I purchased a couch from Mr Price Home. Only to get home and find out that the couch had no legs when I was assembling it. I reported the matter to the store and the store Manager came to my house to asses the couch and he confirmed that not only were the legs missing but the couch was in fact damaged (factory fault) I was assured I would have a replacement couch in 3 working days but now it's been two weeks and I have to keep driving to the store at my own expense to follow up on what the progress is. I was then assured I would have a new couch by today 14/10/2015 but now they have called me with excuses saying the replacement couch is torn. I'm very angry and dissapointed in the service because I'm being pushed from pillar to post and instead of solutions, the retail store is inflating the problem further with delays and excuses.
