DAMAGED LOUNGE SUITE THAT WAS SOLD FROM DISPLAY

Last year on the 27th of November 2023 i bought lounge suite from Beares Heidelberg for R43 000 cash. I asked for them to be delivered on the 28th of December of which they did deliver. 2 months ago i discovered that the couch is has been torn and there are springs that are poking the couch which leads to the couch being torn and damaged. After that issued a complaint about the couch and i even sent pictures to the store manager only to be told that it is "customer negligence", and i also discovered that they gave me this lounge suite that was on display it does not come from the warehouse. I even went to an extent of contacting the headquarters and only to receive the same comment saying it's customer negligence. The effected part is where the couch is curved and that part does not even touch the wall and we even barely move the couch. Therefore i need help about this issue because they're not willing to change the lounge suite or refund me
