Hisense 198L lockable chest freezer

I bought a hisense 198L lockable chest freezer on the 14 of April 2025, it worked for a week, then only the lights worked on it, it does not freeze at all, i lost my meat and veggies that was in it, but its ok, i was calm at that time. I reported it to Hisense and they said that they will send a technician to my house on 9th of Mei 2025, no technician called me and no 1 showed up at my place, I phoned them again on the Monday and they said they will call me to arrange a time to come and see what the issue was with the item, they called me and said they will come on Friday the 16th of May 2025, again arrange my day from work so that I can be at home, at 13H45 I phoned again and they said they tried to call me the previous time to arrange for the technician to come to my place, but I did not pick up the call, this is not true but anyway, they said it's still early and they will still come to my place to check what the issue is, it's nou 16H46 16 of Mei 2025 and no technician was at my place amd no phone call was received to my phone and still have a broken freezer. I am not happy with hisense and I will not support their products again, they need to come and pick up their freezer and refund me, my next step is my lawyers and the rest of social media sites.
