CS6 Master Collection Unable to Activate It on New Laptop

I purchased CS6 Master Collection for Mac back in 2012 through my college at the time. In 2015, I reached out to Adobe support and did a platform swap on the license as I had purchased a new Windows computer. Since then, I have not had a single issue using the Windows serial number provided by Adobe support until recently. 

As tech does, my laptop finally crashed (it's 10 years old now) and I purchased a new laptop. Upon downloading the CS6 Master Collection for Windows as provided in my account because both licenses are registered under my account when going to activate it, it says that my Windows license was revoked. 

I reached out initially to Adobe Chat support (who were less than helpful) and they confirmed my Windows Serial Number has been revoked and only my Mac Serial number is active. They could not tell me any more than that as to why all of a sudden my Windows Serial Number that was provided by Adobe is no longer active and kept suggesting that it was illegally obtained. 

After they accused me of illegally purchasing the software, they said there is nothing they could do and I could still use my Serial Number for MAC if I so wished. I don't have a Mac, I haven't in 10 years. How do I rectify this situation? I don't understand why Adobe revoked my Windows license that they provided me, and now that it is no longer a supported application, they are saying they can't reissue it?

I don't understand.
