Phillips steamer issues and no service by the company

I purchased a Philips garment steamer online for over R3,000, expecting a durable, high-quality product. Delivery was quick and efficient, which initially gave me confidence in the brand. However, within less than a year of use, the steamer developed a defect where the handle started lifting, making it unsafe to use. I returned the product while it was still well within the warranty period. Since then, the experience has been extremely frustrating. Philips has failed to provide any meaningful feedback or resolution. The only communication I received was an invoice, which makes no sense given that the product is still under warranty. When I responded to query this, there was no further communication — they simply disappeared. It is disappointing that a company can act so efficiently when selling a product but completely neglect its responsibilities when something goes wrong. It feels as though the warranty terms are ignored when it actually matters. I am still waiting for a proper response, repair, or replacement. At this point, both the product quality and after-sales service have not met expectations.
