Disappointed Customer / Bad Customer Service

Hi I purchased a Hisense Front Loader on 17 June 2022 and tried registering my warranty on the website and via their email address since 20 June 2022. Their website warranty link does not work. I called their customer care on 28 June 2022, and left my details with Lucinda as the lady (Natalie) that deals with warranty registration was busy. I called again on 14 July 2022 and was advised by Zandile that the warranty dept was back logged and the Natalie was off sick. I expressed my disappointment and frustration to Zandile. She then advised that I have 6 months to register my warranty and there was no other person in the warranty department just Natalie. I have to date not been contacted by anyone from Hisense to have my warranty registered. This is my first Hisense purchase and I am so disappointed with the level of customer service. I need my warranty cover as I submitted my details and required info several times.
