Exactly two weeks ago my Google Account was disable due reasons that till today was not revealed by Google.
When I tried to contact Google I discovered that you simple can’t talk with the team responsible for disabled accounts.
When I ask on forums even in portuguese and english I was told Gmail is not a paid service so they don’t provide any support.
In both cases I point that all other paid services provided by Google is linked to Gmail (Drive, Apps, Play, Music, Developer Tools, etc…), and I can’t access any of then.
I just wanted my 10 years old e-mail address back, nobody cares, they told even paying Google can do anything to accounts and don’t even need to explain you why.
