I agree with the post above saying that if Google believes you, they will respond. I have had 4 invalid clicks from one of my sites (a very new one which does not really have any traffic), and the earnings was 0 (zero). Then, I e-mailed them to ask why. And then they replied like in 1 hour, and told me that their system thought it was click fraud. Then, I replied back saying that it was not (since it was not), then again they replied back in like 1 hour. So, as long as you are right, or as long as they notice that you are right, they will reply to you and be helpful.
