Totally unprofessional, however you don't know the entire background. If it was something like instructed to turn left and the turn was made to the right I think I would probably have been more than a bit miffed.
As Del Prado said, a phone call, of a report after landing would be better.Best thing though would be a visit to the unit involved - also re-instatement of the fam. flight programme for controllers.
BTW, if you are going to make a report it would be nice to advise this on the frequency as you are QSYed.
