AADSTS5000228 blocking Partner Center registration — How to contact support, I tried Chat, Email, and Tool free. I cant get a someone to help me

I am trying to register on Microsoft Partner Center using tenant axltecptyltd.onmicrosoft.com. Every sign-in attempt is blocked with error AADSTS5000228 — access denied to tenant 7ac4df4e-a945-450a-935e-6e2b987b7c01.

A previous incomplete Partner Center registration exists on an old tenant axltec.onmicrosoft.com which I no longer use. This old registration is blocking the new tenant from completing enrollment.

Please delete or disassociate the partial registration on axltec.onmicrosoft.com so that axltecptyltd.onmicrosoft.com can complete MPN registration.
