DEFY SERVICE SHOCKING

It seems to be a common trend now - ZERO CUSTOMER SERVICE! We bought a Defy dishwasher with all the extended guarentees etc ( R800 ) - 18 months later the dishwasher stopped working, so we logged a call with MAKRO - DEFY contacted us immediately and gave us a ref no. A few days later a technician arrived, stripped the dishwasher and found the main PC board to be faulty. Great he had a PC board with him - OH NO as usual it was the incorrect part - now how is that possible as we gave them the model number and everything they needed - still they got the part wrong. Its been nearly 4 weeks since we logged the call and now they say they don't have stock of that part - HOW?? No call from Defy - just silence. I just think the service is terrible and I won't be buying another Defy product.
