Cannot purchase anything on the app store

Question

No one answered my last question, and I am extremely frustrated as the issues I'm having are for pointless reasons.
I uploaded two iTunes/App store gift cards today, worth 30 dollars.
I have been using the device I uploaded them on for nearly 2 years.
I received a pop-up saying I was accessing the store through a new device (I wasn't).
I needed to "verify" my account through security questions. I was unable to do so, (I shouldn't have had to, I was using the same device as always...), so I attempted reset the questions. After I did, and pressed "save" in the reset questions screen, the page just sat there loading till safari said that "this page could not be reached because safari could not reach xxxexamplexxx.apple.com"
So, I tried purchasing what I wanted to purchase again. Now, instead of asking for verification questions, the app store takes me to this dead link:
https://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/wa/SignInToResetQnA?l ocalang=en_ca
It will sit there, not loading, for 10 minutes, and eventually the "this page could not be reached because safari could not reach xxxexamplexxx.apple.com" screen shows up on Safari after about 10 minutes.
This all could have been avoided had I just simply been allowed to use what I uploaded, straightforward.

the app store takes me to this dead link
It's not a dead link. Your Internet connection isn't working properly. Restart the router and the broadband device, if they're separate. If there's no change, see below.
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
