Disappointed in products and services

On the 17th of May I sent an email notifying Delonghi about my Kettle and Toaster that is rusting. I received a response back asking for proof of purchase. I then submitted proof of purchase to show that I have purchased the proof of purchase is however partially faded due to the quality of the receipt. I also sent images of the kettle and toaster in my email. I mentioned that I bought it as a combo and a large sum of money was spent on it. I have still since then received no response as to how they can assist. I mentioned that I bought it at Dion Wired and the store is now closed. I have since then received no response. Not only am I now left disappointed in the quality of my most liked kettle and toaster but now I am left disappointed in the customer service I have received.
