Error while creating a customer with the Microsoft API

Question

Hello,

A client wanted to create a Microsoft Tenant under an undirect reseller. So I used this REST API request https://learn.microsoft.com/en-us/partner-center/developer/create-a-customer-for-an-indirect-reseller. However, there was an unexpected error that occured which did create the tenant but without the default gdap relationship. As an error occured for the creation of the tenant, we were not able to get the temporary password of the admin so that the client cannot proceed to activatethe gdap relationship.

So, do you know which support can I contact so that I can get the temporary password or a new one if it is expired in order to give it to the client so he can proceed with the activation of the gdap relationship?

I tried to go to the support of the Partner Center API but after filling this page:

I got an infinite loading:

Thank you very much
