The support they do offer just tries to get you to use features to increase your ad spend. Also with the new VPN/Proxy they are coming out with the hide ip address you won't be able to block ip addresses of people who keep clicking your ad. I would track who signed up then block their ip from adwords so they would stop clicking the ad. Google plans to make millions providing a service to mix ip addresses and make blocking excessive ad clickers impossible.
