I am sorry for this. I guess you violate the TOS of AdSense. So they have baaned your account. But don't worry, create a new account and try again. This time be more careful about the TOS of adsense. Best of luck
If you believe you did not do anything wrong you can always try to get it back, keep sending them emails, talk about it over at adsense forums, create a scene, make a noise etc. If you did do something wrong then forget about that account (and site associated with it), move on, create a new account under different name that has different address using different IP (or different computer) and most importantly do things differently if you get accepted again.
Well take this as a lesson and I am sure there are other alternatives that can work on your sites as well.
Well thats sad, once banned its really difficult to get back in. Only option now is find something else try Adbrite or Clickbank.
He was talking about his AdSense account. And whats up with you leaving all these weird/unfriendly comments everywhere on this forum? It's not like you're contributing with anything by doing it.
