I really doubt anyone will just pay 3-4$ to help someone out even though it is a little. How is it hard for you to pay that much, even if you are underage.
And from what I am seeing in this thread here
You're friend either sold the account that had a kbot license on it and that was part of the deal and you are trying to scam.
Or you got scammed and want to atleast get the kbot license off of it.
