Google Disabled my Adsense Account

I was totally shocked when I received an email from Google telling me that my AdSense account has been disabled due to invalid click activities!
I checked the terms and condition again and I don't find I have violated any of the prohibited use!
I do admit that I clicked on the ads myself... I find some of the Ads are very relevant to me!
One of them is Pfingo by Starhub in Singapore... Their VoIP rates are very good and I can use it on my Nokia N81 to make Internet calls. It's 2 cents a minute for local calls and some other countries!

I've already made an appeal to Google and hope it will get done! if not, i'll be totally diappointed! Yes... TOTALLY!
