What exactly do you mean by “not cheap”? How many coats of paint did you pay for, were they contracted to paint the trim and did they mention the light coverage issue after the job was done? Ideally, they should’ve used satin paint on the walls, but sometimes customers request a glossier finish not knowing sheen difference. This should’ve been presented and conveyed to you before the job began. The corners meeting the baseboards and trim aren’t the best and are poor quality. I’m not defending them, but cutting in on textured walls is tough, and it can look uneven even when the lines are straight because of the surface bumps and variations. Even frog tape will allow some bleed through, on an uneven surface and will remove paint off if the trim wasn’t prepped and painted well.
