Cannot unlock my Microsoft account, SMS verification not working

Hi, I need help with a blocked Microsoft account.

When I try to sign in, the system asks for my phone number to unblock the account. The first SMS took too long to arrive and when I tried again I received an error message and cannot retry. I tried another phone number but I did not receive any SMS and now I cannot use my original number again.

I tried all support options through https://support.microsoft.com/home/contact
. I changed my password twice, completed the account recovery form, changed the password again, cleared cache, switched networks, changed browsers and used incognito mode. Nothing worked.

When I enter my main number, it shows “Something went wrong” and does not go to the next step. When I use another number, I receive the “Try another verification method” error, even though no other method is available.

My account is still logged in on my phone, but I cannot unlock it on the web or on other devices. I have had this account for more than 10 years and everything is linked to it.

I even created another email to contact Microsoft Support, but it always redirects me to the same link and I cannot open an actual support ticket.

Could someone from Microsoft please help me unblock my account or escalate this issue? I can provide any additional verification if needed.

Thank you.
