Doesn't your university have an online/anonymous course evaluation system? If it does, fill it out! If it doesn't, every university should have one. No one will give a shit if you're just complaining to be a bitch, but if there are serious problems to be found and you're not a single data point, they will take action, whether it be they remove him from teaching the class or otherwise. Sometimes action will be taken and you won't know about it. The best you can do is make sure you back up everything you say with intellectual comments and actual facts. No one will do anything about a bitter student who didn't get the A he desperately wanted but didn't deserve.
