Samsung 40" TV dead

<p>Samsung has always been my go-to brand.</p> <p>I purchased a Samsung 40" TV in June last year. Bearly a year old my TV stopped working. Still under warranty it was booked in for repair at Samsung Grove Mall. The technician said it would probably be fixed by the end of the day. Having not heard from them, we phoned in the next day and he said the power supply had failed and a new one was ordered and would arrive on Monday the 19th of June. Called in on monday... no PSU. Called in on Tuesday... turns out they ordered the wrong unit for my tv and a new one would be shipped overnight. Then the techy told me he could fix my exisiting supply.</p> <p>Being an electronic engineer myself I would've done that from the start. ... It's now Friday and the part that was supposedly sent overnight still has not arrived. The manager and the technician keeps telling us they will phone us back when we eventually do get through to the service centre. But they never do and they can't give you a reliable ETA!! </p> <p>I'm done!! Either refund me so I can buy a better TV or replace it</p>
