Kiwi Juicer Replacement Parts Unavailable for Two Years

I have been using a Kiwi brand juicer and for about two years I have been unable to obtain the chamber and filter as spare parts. Because these parts are missing/defective, I cannot use the product properly. During this period I contacted Kiwi and the relevant service/authorised channels several times. Each time I was informed that they could not supply the spare parts and my request was closed with this explanation, without offering any alternative solution. I request that the chamber and filter spare parts for my Kiwi juicer be supplied as soon as possible, or that my grievance be remedied in another appropriate way, such as product replacement or a suitable compensation.
