Hi All,
I was able to answer my own question.
I had to call Volume Licensing Support to get the MAK keys added to my contract / or profile.
I had tried to call them previously, and could not get past their automated system to a real person, very frusterating.
After about 8 tries (Literally) I just kept saying "volume Licensing" they transferred me to a real person who was able to add the keys to my account.
I was calling the number in this link (same # from my original post). This number seems to be for all licensing and I think that's why it was so difficult to get to the right person for volume license support (Our reseller is the one who gave me this link):

But I think the numbers in this link may be more direct right to Volume License Support. (I didnt verify but looks that way) https://learn.microsoft.com/en-us/licensing/contact-us
Really hope this helps someone, it was a very frustrating experience. For the amount of money I pay for these licenses and software assurance, I should not have to call and ask them to add it.
