Poor service from Busi and team from Beares Krugersdorp

My partner and I bought a couches and other items from Beares Krugersdorp. Months later the couches had "sink holes" and the stitching was coming off. We called them and notified them about the issue. Almost 2 weeks later the accessor was suppose to come for the life of me there's always an excuse why they aren't able to come. My partner escalated the matter to head office. We currently sitting with couches that are not within in good condition and as per contract we are well within warranty.
