Pathetic area representative of Phillips and poor customer care

At end of April 2034 I bought a Phillips 300 men groomer/shaver from Dischem. I returned it beginning of September 2024 to the retailer because the metal blabe protector has worn through. The retailer then contacted the Area representative Chantelle and she just inpolitly said that the head of the shaver is not covered in the warranty because it is a movable part??? The entire thing is movable parts!! What is the warranty for then? I have an incurable disease and the medication I use cause hair loss or Allopecia and thinning of my skin that is why I oppted for an electric alternative simply because of the price of blades and the safety aspect of it. I tried to order the metal foil protector from take alot and The U store in Menlyn and it is out of stock. I then phoned Phillips customer care and had a "I don't know response" which is not good enough for me. They themselves had sent an email to the retailer and stated that the metal protector should last 2 years! There is absolutely no interest from Phillips nor the retailer to refund me or exchange it. The service is aphauling and the area rep completely disinterested. That should I do?
