Why is my Mac locked out of iTunes Match?

Question

I spent the $25 to purchase iTunes Match on my family's shared media iTunes account and the day the service went live. I then set it up with our Mac Mini, the computer that serves as our family's media system. The iTunes account in question is relatively new, only a few months old. Prior to that, my wife and I were using our individual personal iTunes account to purchase apps and media. It wasn't until I realized we were going to need an account we could all share that I decided to create a family account. The Friday after Thanksgiving, I wanted to show my kids "The Grinch Who Stole Christmas" while the adults continued their after dinner discussions. A year ago, I bought that television program from iTunes on my personal account and knew that I could now download it through iTunes. But when I switched over to that account to download it, the computer automatically become un-"associated" with my shared account account and "associated" itself with the old account. And now, I cannot use the account that was used to set up iTunes Match, on the computer for which Match was purchased in the first place. As of right now, I apparently cannot re-connect that machine to Match for another ninety days, which is nearly one quarter of the year for which I purchased the Match service.
I find it troubling that Apple is punishing me for accessing media I have purchased in the past by locking me out of a service for which I have paid. Both accounts are associated with my name, both accounts are associated with the same credit card information, the only thing that differs is that they associated with different email addresses. This all seems very esoteric and not very customer service oriented, and this is coming from an owner of numerous OS X and iOS devices. This is an issue that is going to come up more and more for Apple's customers as more people buy in to the iTunes/iOS/OS X ecosystem and try to make the best possible use and sense out of it all. My attempt to get resolution to my problem through Apple Support was met with a very flowery, "tough ****," from a customer support representative. Neither the choice, nor the response are suitable. What efforts, if any, are being made to try to make this more workable for people like me, trying to make the best decisions while moving ahead in the iTunes ecosystem?
Is there a fix for this, or am I just going to have to eat it and not use the service I bought, on the computer for which I bought it, for a quarter of the time I paid for?

Answer 1

I did contact them. I put in a ticket immediately after discovering that I was locked out. I asked for help or in lieu of that, a refund. Two days later a customer support representative contacted me via email to offer nothing in the way of help and to tell me that a refund was not an option per the iTunes EULA.
I am very disappointed by how this has been handled thus far. iTunes Match seemed like a wonderful service, but being punished for reasons that are entirely unclear, has really soured my opinions about it.
