Damaged goods - no answer on their hotline for 3 days!!!

I have never been this disappointed before - I bought goods to the value of almost R 9000 online. One item was visibly damaged and I refused to accept it. The other turned out to also be damaged once I opened the packaging. The courier said they would replace the items before Saturday. When I followed up with Erol from JKC he said I had to contact Decofurn directly. I have been trying to get hold of them on their national hotline for 3 days and I haven't managed to get through even once. I have no idea how I am supposed to get these items replaced. Terrible terrible service and I certainly will spread the word about this.
