I had no trouble obtaining an appointment at the Genius Bar for later this afternoon.
If the Apple Store is not that convenient for you, check to see if there is an Authorized Apple Service Provider (ASAP) in your area. In most cases, you do not need an appointment, but it would be a good idea to call in advance.

Regarding your question.......we are all users here on this user-to-user site......just like you. Apple is not here. They will not see your post or reply.
We can't answer for Apple, but personally I have always received prompt and courteous service whenever an Apple product needed some attention.
