I bought an Acer C530 PDA in January. The unit never worked as it kept losing power. I returned under warranty and all Acer did was replace the battery, which did not solve the problem. I returned it again and this time they actually realized there was a major problem and replaced the mainboard. BUT they replaced the touch screen incorrectly so that not all was visible/accessible, effectively making it unusable. I tried to complain to Acer but they would not even apologies and were downright rude and have twice put the phone down on me. I emailed their escalations department to try and get further action but they just replied with a stock response pointing out their terms and conditions and not accepting how badly they have messed me around. They really do not have a clue about customer support and are the worst company I have ever had to deal with, they have made me so angry and frustrated. They are not to be recommended to anyone.
