Lack of Service

How can a company charge nearly R2.5K for a Royalty Line pressure cooker but are unable to supply spares for the product? A small seal under the pressure indicator has perished, rendering the pressure cooker useless. After numerous emails with photos to Royalty Line South Africa I have simply been told "We don't have what you are looking for" My request for Royalty Line Switzerland's email address is ignored. Surely seals should be available for an item of that price?
