Why would you purposely choose someone who is always away on trips, giving talks, etc. as a thesis advisor?
At my university, we were not allowed to choose a thesis advisor who was not tenured, nor a full professor. We were also required to submit a one-page synopsis of each research project proposal to our advisor. Then, the advisor would steer us to the appropriate professors for supervision of the thesis. We were able to maintain the same advisor throughout the process.
You said you
She’s proved to you that she is/was busy.
Her area of expertise is not the area that you wanted to do your research.
She tried to tell you what she needs done by having you work with HER Ph.D student. Have you even read/checked your research guidelines packet (what you can and cannot do during research and subjects’ use)?
You want to file a complaint before you even begin the thesis process? Who will be willing to be on your committee after you file the complaint?
Do you know how many people complain about their professors? Why do you think you have a right to vindictively affect her career? Because she didn’t communicate with you??
If she travels often and gives talks, it means she’s popular, and, a university is not going to miss out on an up-and-coming lecturer/researcher.
FWIW: My advisor and I got into deep discussions, arguments, point-of-view transitions, etc. I loved her and at times, couldn’t stand her, but she made my research better. Writing a thesis is not on a semester timeline. Unexpected issues come up during the research, ALL OF THE TIME! If you personally have a timeline, you can walk through ceremonies but finish up the thesis at a later date with university permission.
BS
MS=More of the same.
Ph.D.=Piled higher and deeper.
My advice: Go find another advisor.
