Samsung TV replacement issues

Bought a New TV on Black Friday, which arrived a few days lates. Immediately noticed an issue in the top left corner of the tv. After continues follow ups and calls, A technician was called out to inspect the issue around 17 December. The technician deemed a replacement tv should be issued as the tv is brand new and this is a factory error. Received a call from Samsung call center again the following week around 22 Dec, stipulating that the tv will be replaced and I will receive it in the the week between 25 December and 31 December. So I am still waiting. Called today, 4 January 2023, and now the call center have no idee what I am talking about. This is the case every time. Stay clear of this company, the aftermarket service is terrible. Quick to sell, not quick to replace.
