Samsungs Nature Clause

We bought a Samsung 12kg Eco Bubble Front loader on the 20/10/18 meaning that the machine is still under warranty. Recently we started having problems with the locking and unlocking of the door. We contacted the call centre to which they sent out a repairs team. They found ****roach droppings inside the machine from when we had a small infestation and it was taken care off. We were told that this voids the warranty of the machine. We spent 16k on a washing machine and now it can't be fixed due to something that was out of our control. If ****roach droppings break the machine why is it not built to prevent them from getting in? It's not like the owner can sit in front of the machine and watch it make sure no tiny animals go in. We had defy before this and bought the eco wash due to the water-saving function but now we sit with a bigger problem than water after spending 16k! This the second time that Samsung has proved to be concerned for their own benefit instead of client-centric n space of a month. Bought a Samsung Note 10 3weeks ago and the call centre was the most unhelpful. Thought Samsung was my go-to brand but definitely changing.
