Hello, I just donated 25 keys for VIP badge.
Have read the about how to get the bot.

But whenever I click relocate I got this (403) Forbidden.

And a question for later,
How can I contact or change things like avatar of the bot?

Try to re-login.

Bot profile changes are done via http://dispenser.tf/view_customization/
