power seats, climate control

Can I add Power Seats and climate control to my 2002 jetta GLS 1.8t, the dealer said that they "MAYBE" can do it. I orderd my car from the factory and it took 3 months to assemble but they refused to add power seats and climate control to my package, they said that is did not come in that engine, My argument was that if the car is not put together yet just add it, I even told them that I would pay extra for the mod but they would not do it, I guess you have to be a a big star to get what you want from car companies. Can some one please let me know if it can be done.
