My account is also blocked. Here's the deal.
I run an agency, mostly Google Ads. After pitching Microsoft Ads to my customers several bought in, so i setup my account with Microsoft Ads.
In Google Ads, you can create an ads account, make the customer a billing admin, so that they can enter their CC info, and we can begin managing their ads.
I took the same approach with Microsoft Ads, but quickly realized that when you make customers billing admin on their ads account, they can see all the other customers Names, and CC on file. Yikes. So we quickly had to pivot into another direction.
I setup email groups in O365, one for each customer which allowed me to register an ads account uniquely for each customer, which would resolve the CC problem of each customer. This worked as the customer was able to login and enter their CC info.
Then BAM! My account was locked. I went through a few weeks of support calls, and finally ended up with this email:
Good day! This is Laisa from Microsoft Advertising. I hope this email finds you well. This is regarding the account review.

I've never had such a hard time trying to bring someone customers and money. It feels like an uphill battle with Microsoft Ads. For now, we just have to push Ad budgets that were intended for Microsoft Ads back to Google Ads.
