I am very sorry about your issues. You were trying buy coins using which app?
Please let me know by replying to me here so that I can help you further.
Thank you for writing back with that information. And you are using iTunes on your Windows 10 computer, right?
If yes, can I remotely access your Windows computer so that I can directly assist you in fixing the account problem while you watch on your screen?
