Why are repairs not being adequately addressed for devices under warrenty and how can i get...

If the console is regestered and still under warrenty then you can sign into your microsoft account on a computer , locate the my devices tab, and should be able to request a repair. If not under warrenty yhen try finding a local computer shop that can
do the repairs. If you can do it yourself then buy replacement parts online and have at it , but i would try to have someone else fix it as they would have to make sure it works before you take it back

I would try the adapter as it would be more cost effective than getting another controller . Also check to see if the controller is under warrenty to see if you can send it in for repair

do a repair service request it should still be under warrenty

If you did not properly vetalate the console then yes its your fault but you can try getting it repaired... it should be under warrenty still. Did this happen after an update?

It is registered. The support site see's my device under my profile. The link you sent is taking me in circles back to the Create a repair order that I am being blocked on. I am not able to get past the Add your address.

If i knew where i could set my address in my profile so I can use that address from the drop down menu, that (in theory) would get me step 2 of the Create a repair order process.
