I had someone step in and help me. This has to be handled through support as they are the only ones who have access to the color matched accessories. If you call support and ask to speak to a supervisor have them reference the following Apple article: CP403439. They can read it on their end and I guess it explains to them how to do it. A line support person won’t be able to help you so make sure it’s a supervisor. The overall gist is that when you order a replacement mouse or trackpad they take a credit card on file. In the event they don’t receive the bad one back in the mail then they charge for the new one. In our case, there is no bad one to return so that is what will happen. They have to ask a couple CYA questions like you said you old one just stopped working, right? Just play along with the supervisor and that will finally get you there. Again—the whole process is screwed up from the beginning and their ordering process.
