Asked them to replace the battery on my MBP (out of warranty), got it back with non-functioning USB ports. Had to return it 3 times, every time I got it back I tested the USB ports inside the store only to demonstrate that the problem still wasn't fixed. Eventually they even tried to convince me that this was a software bug.
After 6 weeks without working USB ports I got really angry and they finally agreed to replace the broken motherboard. When I got it back my laptop worked but it had a different keyboard installed (Dutch, instead of US intl). I complained about that and they told me that I was lying (even though a had the purchase receipt with the US keyboard option).
After that I gave up and bought a Lenovo, haven't looked back since.
The service in Amsterdam may be better, but traveling to the city center of Amsterdam twice just to get my laptop repaired is not acceptable.
