Apple Store 4+

I am new to iPhone. Everything in this phone is oriented at the idea of my opening my wallet. Only when there is no other choice, inquiries about my needs are made.
For example, when one buys these phone there is an avalanche of apps, widgets and sales ads everywhere. So the user finds itself with a phone in his hands with no idea on how to make a call.
After much embarrassing and asking strangers, the user proceeds to get rid of all garbage apps. Then it finds that the text messaging app is nowhere to be found. But it had to be somewhere, when buying the phone the clerk at the store used it! So now the user goes to the App Store to reload the message app that came with the phone. And so where is it?

My son had bought a brand new phone from working at the library. It was an iPhone XR. A year later right after the warranty expired his Face ID feature didn’t work anymore. We called customer service and we were put on hold and were talking to many different people for hours trying to figure out the issue until the Apple “Senior Advisor” called it a hardware malfunction. She said that it won’t get fixed and that we would have to pay $399 dollars for a replacement. Is this some kind of joke. Or even better a pyramid scheme that as soon as the warranty runs out let’s destroy an innocent kids phone so that the kids parents will buy him the new phone. DON’T EVER BUT FROM APPLE!! It’s nothing but a scam. I was disappointed especially because this wasn’t my first Apple product but my sons first Apple product.

Unprofessional Apple staff and DO NOT deposit your Apple gift card balance into your Apple account.

I was told I could use my Apple account balance to pay for my iPhone repair, but when it was done the second day, I was told I couldn't pay from my Apple account balance. However, I could have paid for the repair if I hadn't deposited my Apple gift card balance into my account. And eventually, I paid by my own credit card and left the Apple account balance unused.

In short, once you deposit your gift card into your Apple account balance, it will have very limited usage. You can't use it combined with installment, can't use it for repair. That's just from what I know. Come on, it is already 2022, how can Apple hasn't fixed it? How can staff's answers be so confusing?
