Poor quality appliances

I am writing this out off disappointment brought by HiFi Corp, i bought a Sinotec soundbar system exactly a year ago (30 October 2020) for R2699 and today I'm here heartbroken since the system only fully functioned for the 1 year warranty period and started being defective on the 1st November 2021 and now I'm expected to pay monies for diagnosis/repairs for a low quality unit they sold me! Mxxm Hifi Corpss are ****ers when it comes to electronics
