Steering Column problems of the 2013 Toyota Corolla

I noticed a rattle sound around steering wheel so I took Corolla to service department. Technician was able to find the rattle. Dealership service center contacted Toyota and they we're advised to replace my entire steering wheel column. The rattle sound is gone but since they replaced the steering wheel column there seems to be over rotation of the steering wheel (meaning I have to turn the wheel more than usual to make a right or left hand turn), steering wheel will not return to the center like normal and makes a rubbing sound when I turn left or right while parked or driving at very low speeds 5-10 mph. Technician and service advisor stated they felt the car drove fine and that they did everything they could to remedy the problem. I will be taking my car to service department one more time to see if they can figure out what the rubbing noise is and why my vehicle steering is not as it should be.
