Won't sell internal parts for self repair.

Nespresso say they don't sell internal parts for Nespresso machines. I need to pay R900 plus VAT for a "Service" and then they will determine what's wrong, repair it, and I will need to pay whatever they charge. I've opened the machine, and it's a simple plastic part that has broken. I can buy the part on Ebay, but with exchange rates it very expensive. Don't buy machines for which they refuse to supply internal parts. You don't need to be a rocket scientist to repair these things. They just hold the manopoly. Will 3D print a replacement which will probably outlast the original.
