iPad Air (Can't attach photos)

I bought an iPad to record games and upload them to YouTube. However, starting the day after purchase, when I tried to record the screen, the game audio wasn't captured properly, only crackling noise was recorded. If I turned on the microphone, the sound came through, but the audio quality was so bad it was unusable for broadcasting. At first, I tried to get it fixed and contacted customer support multiple times, but it wasn't resolved. So, a little over a month later, I requested a refund. I was on the phone for over an hour, but they only replied with, "You can't get a refund for a change of mind," and "You have AppleCare, so get it repaired." I visited a service center, but they told me to contact customer support again. In the end, they told me, "We don't know when the update will be, so just use it as is." This is a functional issue that started the day after purchase, yet they couldn't fix it and treated the refund as a change of mind. I experienced significant inconvenience during this process, and I'm extremely disappointed with Apple.
