I don't think you've provided enough info here.

Was your car sitting at the dealership awaiting parts that were specifically ordered for your car, or were you simply waiting on the dealer to give you a call when they had parts available?

It's understandable why the dealer would want to fix their own cars, so unless they somehow used your VIN to get extra parts and then did not follow through on installing them in your car I'm not sure what there is to get upset about.
