Complain

I bought couches last week Thursday the 10 of Nov and they were delivered on Friday, I told the delivery guy that I am not happy with these couches and the quality is not the same as the one I saw in the shop. I then called the sales man he said I should come to the shop for some paper work when I got there they didn’t give me anything instant they told to live my details they will send email to the head office that was Saturday and they told me that they will communicate Monday because they do not open on Sunday. Monday they kept quite the whole day I then texted them Tuesday and asked about the progress because I have a kid that might mess these couches. Even today I still have them. I want them to take their couches and bring back my money
