Claim declined . Dishwasher returned damaged

My claim was submitted on Monday the 9th of February, my dishwasher was collected on Tuesday and returned to me on Thursday. They told me that they cannot fix my machine and that I should take it to a Samsung outlet to get them to check it out for me. On top of that, on inspection of my dishwasher I realized that there's *****s missing on the back so the side panel is loose and the front area that you grip to open the door is loose or broken and the clip is broken on the part where you put in your dishwashing tablet. I am really disgusted with the service. What's the use having home contents insurance when they don't cover your home contents. They say they cover loss and damages. My dishwasher is damaged. I want it to be replaced. I have \insurance"so I don't have to run around with issues like this. Why am I paying a premium every month then. If I'd known that this would be the outcome down the line"
