While your general idea is correct, the way you communicate it is needlessly rude and contrarian. The better way would be to answer, that yes, surely you will help, but there doesn't seem to be a valid M&S contract in force and that you will gladly discuss specifics with them, if they are interested. See? That's the talk the managers understand, they don't work for free either. So it is either an important thing they need to fix and will work with you, or it is not and in that case you will not waste your time. The simple thing is, that you need to recognize when they exert pressure on you and then simply mind your own interests.
