complaint

Apple does not have a general email address for complaints (or for anything else, for that matter).

Like just about every large company Apple has both formal technical support and an area where users can discuss technical issues with other users. And, like all of those other companies, Apple does not participate in any significant way in the user-to-user discussions, as that might inhibit the free flow of ideas. The formal name of this area is Apple Support Communities. The “Communities” should be a giveaway that this isn’t a formal support site. And if that doesn’t, the site itself is https://discussions.apple.com. The “discussions” is another giveaway.

Apple’s formal support can be reached several ways:

• You can provide feedback to Apple at→ https://apple.com/feedback where your issue or suggestion will be recorded, but you will not get a reply

• Click on “Get Support” at the top of this page
• Go to Apple Support

Note that both of the above have options to receive a callback or chat

• Install the Apple Support app on your iPhone or iPad - you can contact support directly from the app, and the tech will have (with your permission) the ability to diagnostic data on your phone
• Call Apple Support; the phone numbers are in this link→Contact Apple for support and service - Apple Support
• Make a Genius Bar appointment at an Apple Store→Genius Bar Reservation and Apple Support Options - Apple
• Find an Apple store or Apple partner service provider→https://apple.com/retail
• DM @AppleSupport on Twitter

About the only communications method not used by Apple support is inbound email, probably because the volume would be overwhelming, and separating the wheat from the chaff (or, to us engineers, a poor signal to noise ratio) would be almost impossible. 

If you'd like, you can submit your comments/requests to Apple directly, using this form:

Apple – Product Feedback - iPhone

That will be REALLY effective.

or you could email Tim Cook. You can easily find his email address with a web search. He or his executive appeals staff will usually respond to reasonable messages, except to rants.
