If there is nor resistance whatsoever then I suggest that you have the front of the car jacked up and wheels off the ground. That would be my understanding of 'no resistance whatsoever'.
When you turn the steering do the front wheels turn ?? They should, therefore there must be some resistance. Seems to me that you don't really have any idea of what to feel when turning the steering wheel.
Take it back to the workshop that did the job and have them check it for you - after all you paid to have it done (correctly).
