You sent in customer service tickets to why you cannot login, not a ban appeal.
I sent one of those too about a week ago and it is still "Open." But my ban appeal is already closed w/ no reply.
The ban appeal is automated, it runs a check on your account I believe to check if some things are too high over a set threshold.
The only way to get around a ban is to not get caught xD
Yep, we've known this from the start. They really have terrible customer service. Someone should Tweet john or nianticops and ask them why they have such shitty customer service xD
