I know that it is my responsibility to get the clearance
before flying into the airspace, but if they are giving vectors to
penetrate the airspace, are they at fault as well? Maybe I should
file a NASA report just to be safe, what do you think?

Yes, file a NASA report. They shouldn't vector you into the Bravo
without giving you those magic words, but it happens.
