My phone-number is unavailable to verify my Valorant-account?

I had disconnected my phone-number from my old account months ago and yet I am still being told that it doesn't work to connect my phone-number to my newer account.

Does anyone know what I am missing?

Solution

How many months are we talking?
Cause once you unlink a number you need to wait 6 months before you can link it to an account again
