not only

Not only was there no apology or even acknowledgement regarding my broken item(s), but as I suspected, I had to clean all the broken bits up myself. One thing that was broken was a ceramic frog, which granted I didn't really even like that much, but Sarah told Betsy that she broke it, but that it wasn't her fault and that I would figure it out. I just don't understand her, I guess if she doesn't feel sorry, then she shouldn't apologize, but at least take enough responsibility to clean it up, does this not make sense?
