[FIXED] Can't purchase My First Pet

I have Sims 4 with the Cats & Dogs Bundle on disc installed, and I have never been able to install just the My First Pets Stuff pack. According to EA back on their own site on March 31:

On Xbox One

To get the pack on your Xbox One, you first need to own or purchase Cats & Dogs. For $39.99, you can get a bundle including both packs. If you already own Cats & Dogs, you’ll still add the bundle to your cart, but you will only be charged $9.99 for the My First Pet Stuff Pack.

Supposedly I was to be able to get a discount on the Bundle to make it $9.99, but  this issue has never been resolved, even though the problem has been going on for going on over 3 months. I opened support requests with EA, they blamed it on Microsoft. I opened a ticket with Microsoft, they blamed it on EA. So clearly neither side is concerned or really cares to get it fixed, so I guess they don't need the money. Pathetic, really....
