so many banner and if i change plan so small mb. how do i closed my account
You said you are on the advanced plan - there is no banner. If you are on Corporate, there is.
I am a bit confused on what you mean by "So many banners" - there aren't. You are just required to put the ad code on each public - viewable page. Thats just one banner or text link.
I can close your account, but I am hoping we can work through this issue without having to resort to that.
Edit:

so many hassle and must follow rule, if i change plan so small mb. how do i closed my account
Unless you plan to host your website on your own computer, you are going to be required to follow a set amount of rules no matter where you are hosted. You could switch to a paid hosting plan, which - although still has rules ... does not require you to have advertisement. ( And would also give you the needed space and bandwidth you ask for )
