Please give me back my furniture

I purchased a lounge suite from House and Home Fleurdal. In only a short while two of the couches seating broke (They call it sagging). Two of the armrest material were also damaged. 6 WEEKS AGO they promised me that it it will be repaired after receiving the necessary report. A promise was made that the repair time will be no longer than a week. It has been 6 weeks now. I have been struggling since June 2015 with this. A promise was made that it will be delivered on 21 August (last Friday). Today is Wednesday - I HAVE NOT RECEIVED MY LOUNGE SUITE! After many calls and promises and poor customer service - nothing!
