Hey @xkai 
From your post, it looks like you took every step you could to rectify this and the support received was just really poor, and the handling of the problem was even worse 
I would suggest filing a complaint. Not only to get a solution,
but because they well deserve it.
A link for doing so has been previously posted on the forum, but not officially. If you wanted to file an official complaint, you should clearly tell an agent your desire to do so
