If you have things in writing regarding the amount of photos, that's contractual. 460 doesn't even seem like enough for a communion, let alone 3 days of a wedding celebration.
Has your photog communicated anything to you regarding why, or if he will provide you more photos. Unfortunately, when we don't get to choose our negatives, it gives the photog the responsibility of this decision.
I would call and write and express your dissatisfaction. Hopefully he will accommodate, as any professional should.
