Reindexing the steering wheel on the steering shaft IS NOT THE PROPER WAY TO CENTER THE WHEEL! Steering gears have "high spots" in the center to create a nice tight feel when driving straight and the steering systems on cars are indexed to assure proper assembly to keep the wheel on the high spot in straight ahead driving.

Verify how the wheel was centered and if the steering wheel was reindexed on the shaft, suggest you read the service manager the riot act, and have them do the job right by adjusting the tie rods.
