Account email transfer issue

Ok so I had two Microsoft accounts. Both are my personal accounts, so the first account used my primary email. Then, my dad and I tried something on my Xbox 360. This was very long ago, and he changed my gamertag and put his username into that account (basically the gamertag I didn’t want). Now, we had to pay to change it again, and at that time, we didn’t have any money, so I went and made a second Microsoft account with a Gmail email to get my preferred gamertag, and I linked all my stuff onto the second account I made, like my Minecraft, which is the area of concern at this moment.

So what I did today is I swapped the emails on the original account. I created an alias email that forwards to my primary email (NOT THE GMAIL ONE), and then I put my primary email onto the second account where my Minecraft and stuff is linked. But now it says I don’t own Minecraft anymore, but when I log into my Xbox account, I do see all my friends there that I played with, so I am on the correct account, but I also don’t see any games. I did remove the Gmail email as an alias from my second account, but it still wants to send a verification to that email, but that is not my main concern. It is the fact that I lost access to my Minecraft licence. Please assist.

P.S. I am not sure these tags I selected make sense, so hopefully it doesn't screw me over. I am also writing this on my second account, the one where I put my primary email on.
