Yes, tact goes a long way, hold them on any and all technicalities, begin with "What is your Role?" and press for clarification for everything they expound with to that question. If they don't state their role, their capacity, then alarm everyone This you are forced Against your Will by People acting in an Undisclosed Capacity, and don't stop until someone listens to you, demand your rights, detest and object to any acts denying you your rights.

It is better to suffer every wrong or ill, than to consent to it.
An error not resisted is approved.
He who is silent appears to consent.
Things silent are sometimes considered as expressed.
To conceal is one thing, to be silent another.
Concealment of the truth is (equivalent to) a statement of what is false.
Suppression of fact, which should be disclosed, is the same in effect as willful misrepresentation.
Evil is not presumed.
It is safer to err on the side of mercy.
