how long am I banned for?

Right now, it is uncertain, so please make proper ban appeal if you wanted to be unbanned.

(also it is not my ban)

Do you know who I should contact?

I am sorry for the tk kick, won't happen again.

You are in the right section where ban appeals go.So make a proper ban appeal and wait for an admin who did ban you.That is all you have to do.
