License Nightmare

Im a user who has purchased a license and there’s no direct way to confirm my serial numbers with my accounts. They were purchases a few years ago and we recently rebuilt a users Mac and now the SNs aren’t recognized?

HELP!? is there someone to talk to?

Is there anyone out there who can help me match my purchased serial numbers to my account? They are not showing up!

HELP PLEASE

If the serial is not there, it’s probably purchased by another account
