Poor Service from HISENSE(***)

I'm so disappointed with treatment I received from HISENSE, my TV stopped working and I called them since I'm still covered in terms of warranty. The problem started from day 1 when I called them to report it as I was sent from pillar to post, later they sent someone to come and collect the TV on the 26th last month. Last week I was told that the TV is fixed, they're busy with tests and finalizing eveything and it will be ready on Monday(09/10/2023) for it to be delivered to me on Tuesday or Wednesday latest. Today is Friday(13/10/2023) and I haven't heard a word from them, when I called them today they said it is still at Service Centre and waiting for technician. HISENSE you have failed me and I wouldn't recommend anyone to use or buy your products.
