The recommended way to resolve difficulties is to use this forum and quite frankly, it's a better bet than "contacting Apple".
What exactly is the problem? If your problem does need specific help from Apple, such as getting fixed under warranty (or even out of warranty), then soemone here will be able to point you in the right direction. Don't forget, there are many different parts to Apple, so even if you
do need to contact them, you still need to go to the correct place.
