Azure SMS toll-free number verification rejection

Hi,

I need help with getting my toll-free number verified. I have submitted the regulatory documents for verification, and my application was rejected with the reason "546 - invalid information - can't validate url - website is not accessible / not available". I have provided three urls in the application: The website portal where users can log in to sign up for SMS notifications (along with the credentials to log in to that portal), and two OneDrive links to screenshots showing the opt-in messages during the signup process (accessible to anyone with the link, verified with a private browser window).

I have verified all three of these urls work every day while the application was pending, and they are still online and working now. I don't know which url they were having issues with, or what else I could do to get this application approved. I looked into submitting a support request to Azure, but apparently that is a paid service that I do not have access to.

Just for some additional background - this is for a private non-commercial system for my local neighbors to monitor their water tanks and water level in our shared spring. I'm funding it out of my own pocket for the befit of our rural community and is not for use by any company, so I'm trying to keep costs down as much as possible. I don't actually need a toll-free number, but as far as I know Azure only allows sending automated texts from toll-free numbers currently, so I have to go through this process. The verification application seems to assume you are applying as a company though and does not allow for the possibility of a private individual using the number for a non-commercial application, which may be part of the problem.

My application has now been rejected twice, for the same reason and with identical messages. The first rejection was valid, I had inadvertently shut down my web server VM without realizing, so they would have been unable to access the portal. However I turned it back on and verified everything is accessible before resubmitting the application, so I believe the second rejection was in error. Do I just resubmit the same application again, or what could I do differently? Is there a way to get in touch with someone at Azure to look into this without having to pay for a support agreement? Thank you!
