Vertical front brake pads
Your intuition is correct those pads are not right.

The long part of the pad should follow the rim, like this:
(not exactly the same brake but the pad alignment is similar)


You can:
- take it back and let them straighten the pad.
- Use a 10mm wrench, loosen the nut, turn the pad and set it to the correct height and tighten the nut.  

If they did this wrong it would make me nervous that there are other things they missed.
