Poor customer service by Samsung South Africa

I reported a faulty Samsung washing machine on Monday 11 Sep 2023 to their call centre ***. On 12 Sep 2023, their service department called me and conducted an online diagnosis. The conclusion was that the job would be allocated to one of their agents to send a technician to repair it. They gave me ref no ***. Since the above report on 12 Sep 2023, no one has contacted me and the washing machine is still unrepaired. I have called Samsung on the 20th and 21st of Sep, and the agents have promised to escalate the matter. Two days later, no one has called and the problem is still there. What a ****py service from Samsung South Africa!
