terrible customer service, ignore calls, don’t deliver even after paid full price

We ordered and paid for my furniture on the 29/11/2017, was told that it would take 4 weeks from when payment was made, but for deliveries before Xmas, we can pay an additional R300, which we did. I touched base with them on the 11/12/2017 And was told that all Jhb deliveries were going to be done the following week. They were not. I then kept following up and they assured me that they had a lot of orders but were going to work throughout December to ensure that the deliveries would take place in time. Still assuring me that I would receive my order before Xmas. Then, just before Xmas we got a long email with excuses stating that they will not be delivering before Xmas after all, in response I asked WHEN my furniture would be delivered, they could not give me a date, I asked over and over simply for a date that I could expect my furniture with no response. Finally after threatening to go to social media I received an extremely rude and nasty response. Finally I was told that my furniture would be delivered on the coming Saturday-I has asked in the beginning for my delivery not to come on a Saturday (for religious reasons) the response once again was very rude. And here we are again, instead of delivering the furniture a day earlier or later, my furniture is still not delivered and I am still not recieving any communication on when it will be delivered. I would not recommend them to anyone, their weak work ethic, nastiness, lack of delivery and communication is terrible.
