HELP - MS Vetting Process Cancelled

Actually it is a good sign that it was cancelled - now it is your task to stress every support channel you can find to proceed with it. Our vetting process was also cancelled and after a week they finalized the account.

Look in the internet who you can call, contact better business bureau tell them about your incident. Call internationally not only in the U.S. other countries sometimes have open channels to the actual support guys.

This entire process is a disaster... but we are fully authorized after 3 months.

through bbb.org they can also contact the vetting department through another channel, however it somewhat takes a week to get an answer there.

Another communication channel is the Microsoft support on X, use every single channel you can find stress them to do something otherwise you will just end up in a loop with them.
