Terrible Hisense Customer Service

Got the worst service from their call centre regarding a warranty issue. On April 01, 2024 I sent an email regarding a warranty issue, I only received a response to my query on April 10, 2024 requesting further information like my contact number, address and purchase invoice, which was provided on the same day. I received zero feedback and on April 25, 2024 I called their contact number and spoke to and was promised an email within 30minutes, which never arrived. Today (April 29, 2024) I call the centre again to follow up and none of my details were correct and spoke to the rudest agent ever, Nhlanhla, his supervisor was suppose to call me back but never did.
