Hi Terry Armstrong,
I understand how frustrating it can be when you’re already trying to get a screen issue resolved and then run into difficulties with the support site as well.
As a forum moderator, I don’t have access to accounts or the ability to submit repair requests on your behalf. If the online service request continues to give you trouble, another option is to bring the device to a Microsoft Authorized Service Provider. They can check the device further and help guide the repair from there.
Hopefully one of these options will help move things forward. Thank you for your understanding.
Best regard.
