I am not legally contesting them, but I am discussing with them and now with the employment service also at their recommendation. I will see what comes of it. I was given the option at the time to apply with my work permit/employer or as family regroupement and they recommended I do it as family regroupement because it was easier. I was not informed that this would invalidate my time working towards my C, so I am seeing if there are any options. Perhaps not and it was just a bad choice on my behalf, but non-the-less I am looking now to switch off the family regroupement to my own permit so I'm not stuck in student status another year.
