Terrible Online Service - Don't know When My Furniture Will Arrive

This has been the worst online shopping experience I have ever had. I ordered three weeks ago thinking my order would come together and each item had been split. Whilst the orders were so random with little notice on delivering. I received the cheaper two of the lot. They have the wrong postal code stored in their system for Bloubergstrand which lead the Courier to call me and need clarity on whether its Cape Town or Durban but it is Cape Town. I had contacted them to change it and the man was very rude on the phone and put the phone down on me. He did not change the postal code. I have tried about 20 times to reach them on call and whatsapp and email and they are not responding. My couch was meant to be delivered yesterday and I heard nothing about it, I called the couch company directly and the couch is ready and they just not sending a courier. The TV is nowhere to be found and no indication that its arriving. I am currenly with an empty lounge and this has completely taken away from the excitement of moving into a new place. Its just been a struggle. I now have to wait and see what happens with NO indication of when its arriving and the customer service does not exist.
