The Apple Support Communities are an international user to user technical support forum. As a man from Mexico, Spanish is my native tongue. I do not speak English very well, however, I do write in English with the aid of the Mac OS X spelling and grammar checks. I also live in a culture perhaps very very different from your own. When offering advice in the ASC, my comments are not meant to be anything more than helpful and certainly not to be taken as insults.
Apple doesn't usually repair iPads, they are replaced with new or refurbished iPads when dealing with an iPad still under warranty. Is this iPad still under warranty? If not, then you would need to buy a new iPad yourself. If replaced under warranty, it is my understanding that the replacement duplicates any engraving on the device that was done by Apple when originally ordered.
Did you, double tap your home button to bring up the task bar, then swipe the taks bar apps all the way to the right to reveal the last icon, touch it and then see if your orientation is unlocked?
If you did and orientation is still locked, you should make an appointment at the Genius Bar at your Apple Store, I found the following from an Allan Sampson post on this topic:
If your original iPad was personalized by Apple and you arrange service by calling Apple Technical Support, you will be asked if you want your replacement iPad to be personalized with the same text. iPad personalization is not available in all countries or through Express Replacement Service. If your original iPad was custom laser engraved by another company, your replacement iPad will not be personalized.
