Why can’t I login?

I received my Amazon seller code in the mail almost 2 weeks ago and after entering it, I haven’t been able to continue past this page where it says all my info has been verified but at the top it says “Something went wrong, please try again later.” I’ve emailed Amazon about it but nothing seems to be working. (I would attach a picture of the page but this sub doesn’t allow it). I’ve cleared my history, I used another browser and even two other devices with no avail. Would I be able to create a new one since I technically haven’t been able to fully access seller central with this account? This whole thing has been very frustrating.
