You might be able to return your system to the Apple Store or third party retailer you bought the machine from. If you bought Apple Care when purchasing your device, simply contact Apple directly, and you’ll receive the help you need. Even if you didn’t, chances are there is still an active warranty on your device. To check, open Settings, General, and then About. Tap on the button that says something about “Device Coverage”. That menu shows you information pertaining to your device’s warranty. Keep in mind that there is no guarantee your device will be eligible for a free repair or replacement. I hope this helps!
Take care!
