Recurring Fault

We bought a Samsung ME9114W microwave in July 2013 from Game in Canal Walk. The circuit board stopped working in November 2014 while still under warranty, and was replaced. A couple of weeks ago, the same problem resurfaced. We took it to the Samsung repair outlet in Parow, who quoted us R680 to replace the circuit board (again). This is not significantly less than the cost of a new microwave. They have also levied a \repair rejection"fee of R175"
