Hisense after sales service

In January 2022 I bought an Air Fryer which I love. However the rotisserie forks do not lock so I cannot use them. I also want to buy a spare set of trays. I opened Ticket: 423383 but no one has contacted me. The only email that I received from Thuli at Hisense was that the parts are not available why am I not surprised. It would take 7 weeks. After 8 weeks I had nothing so tried to call her but she was always in a meeting. The operator would take my phone number and email address AGAIN but I never heard from her. The next time three weeks ago, I tried calling AGAIN but she was in a meeting. Fed up now I asked to speak to her Manager but they were in a meeting. Non-existent after sales service. Their online form doesn't work either. I will take this matter to Hisense head office in China that they need to sort out the terrible customer service in South Africa.
