iPhone X with 11.1.2

okay i tried submitting the RMA today from the iPhone - where it asked you to upload the proof of purchase, hello, I cant access my iPhone…lol

Anyway I did it by using my PC

Now it replied me asking for my Phone number which I already filled out on the RMA form

Nevermind, I replied that email and guess what? It says Receipient Mailbox is Full. Please try again later…LOL
