1- Getting on with or not makes no difference to your actions. The answer required is to do what you should do. Point out you are outside the parameters and insist on what you should do. I do not like the idea of wrestling with the controls and it should not be done unless there is significant danger from those actions evident. On the ground you should as a priority report the matter further before continuing.
2- Orbits are actively discouraged these days. If you are in a position where you have to orbit, you should go around and try again. You should call Go around and insist, if not and you feel any risk, forcibly take control and announce what you are doing. Full reports and ASRs will be required, report to Flight Manager before continuing.
(the word required is 'discretion')
