I have attacked some guy who is level 164 and then he posted on my wall. It is the best post ever in my wall. There it is:
"How is it possible for you to attack me when I am level 164 and you are 179. I'm writing to Funziosupport.com, this is not right. I think you are cheating."
No wonder why support always take a long time to reply due to this kind of 'cheating' report.
