Essops not delivering after full payment

I bought furniture from Essops on 27 June 2015. I was quoted 5 weeks delivery. After 5 weeks no delivery, i gave them 2 weeks extension. In the 7th week they were suppose to deliver on the Friday, they arrived at 19:30 Friday night. Half of the furniture was wrong, there was not enough bolts and nuts to assemble the furniture. The workmanship was extremely poor. Some pieces not even the same size I then agreed with them to collect the stuff and fix it up but they had to do this within 7 days which they agreed to. On the 7th day Adilla the COO phoned me and asked for 2 more days extension which i agreed to but i asked for delivery on the Thursday before 12:00 as i was going away on a long weekend. They did not deliver, i started phoning Adilla from 14:00 to 17:00 but she refused to take my calls even though i could hear her in the background talking, i left messages for her but she did not respond. On Monday 31 August i got hold of Cassim 1 of the owners and he promised me feedback a.s.a.p. I have still have not been called by any one at Essops. So they have still not delivered my furniture or refunded my money as i asked. Not even an apology from anyone at Essop
