My admob was shut down by google, I didn't do anything wrong, I don't even know why

Where can I complain about my admob account being closed due to invalid clicks? I didn’t click at all or my friend didn’t click. You know it’s not $10,000. admob thinks I clicked on invalid clicks to increase the dollars. Why?
A: It’s common for Adsense accounts to be closed for invalid activity, and sometimes it’s not the result of you clicking or encouraging others to click. There are many factors involved and I can’t tell because I don’t know your situation.
