Steering wheel crooked and bad straight run

I was looking and found some but not really accurate. Had changed the track rods and had the track adjusted, 65€ for tires Diehl. Result: steering wheel tilted about 10° to the right and he pulls also while driving to the right. Not when braking! Again on ,Recall. All values to 99% exactly. Result as before. Let the steering wheel check again last week, the steering wheel is still wrong although it has been fixed and it pulls to the right…again What the hell is going on with the drill! Now an acquaintance meant that at Opel basically 80kg are placed on the front seats. And that was not done with the meanwhile 3 settings. Does anyone have a plan?? Mfg
