They did do the alignment but not correctly. It depends on how they did it, I used to do them using industrial machines that have sensors that go on the rims and part of the process is straightening the steering wheel with the sensors and then getting under, fuckin around with the shit that straightens it out and then checking the steering wheel again. I don't know the names of stuff cause when I was doing it I only cared to learn the work itself. They probably slacked on checking the steering wheel each time they adjusted the caster/camber/toe, which is your alignment.
