Terrible customer service - Samsung

My name is Andy. I bought a 75inch QLED TV from Makro Vaal in November 2020 and it stopped working on the 2nd of January 2021. I reported it to Makro Vaal the next day. The told me that Samsung will come and check it within 72 hours which did not happen. On the 7th of January I received a call from Mpho from Samsung who promised me that my TV will be checked on Monday 11th of January. When i followed up I got told that the service order number was cancelled and will be re-instead for the 13th of January 2020. I have been calling them since this morning to get an update and I'm still told that the order number still show cancelled status. Mpho did not even bother to give an update on the matter. I am highly upset with the Samsung customer service
