Sea of Thieves tryout problem

So, i got a code to try out Sea of Thieves for 2 weeks, after i installed it, I started the game. Then i got the notification that i cannot play games due to my privacy settings on my account.

When I wanted to log in into my account to change these settings, I had to update my phone number, since I got a new phone.

Now, I cant access my privacy settings for 1 month because of the recent change in my phone number.

This means during my 2 weeks of tryout, I will not be playing the game because of my privacy settings, which I cannot access due to the recent change in my phone number.

So basically the tryout was for nothing, and I cant access my old phone number anymore.

What now?
