Frankly, I don't know what action to take. I have spoken with Apple support several times, with the Apple retailer/dealer and was on various Mac forums for advice.
The answer is always the same: you can't improve the camera, you can only buy an external camera, you have to buy a completely new Mac with a different camera, you shouldn't be so obsessed with brilliant pictures etc.
So what can you do? I bought a MacBook Air two weeks ago for almost 1400 euros and I'm also puzzled by some of the answers from Apple.
