Moving up in the workplace

So my wife works for a fairly big company, currently at a more entry level position as this is what we decided would be best for our currently family situation. Over the last couple months, she has applied for positions that would be a step above hers, comparable to a team lead of sorts. They have a three step interview process and has reached the second step multiple times but never receives any sort of rejection notice or any other information as to where the process is at. Now on multiple occasions, a couple weeks after the first or second interview, the position gets cancelled, then a day or two later an exact same position is available again reporting to the same manager where the previous position was. Since this is a "new" position, the company requires her to follow the standard process for an internal applicant which is the three step process.
It seems that they just keep having these positions "open up" to give the interviewers practice while never intending on hiring anyone. I told her to send a bitching email to HR as all that is needed would be a rejection notice as to why she didn't make the cut or why the position was cancelled.
Anyone else ever encounter something similar to this or able provide any advice for me to relay to her?
