Something similar happened to me LONG ago. I honestly don't remember which event, but it wasn't GAS. Support eventually fixed it, though it took a long time. Several weeks, I think.
I'm not saying it will take you the same amount of time, but I remember I had basically given up and then a while after that... I just got a message out of the blue saying it was fixed and it was.
I hope it doesn't happen the same way for you. I hope you get good communication throughout But also I think you should know that just because you're not getting communication doesn't mean your problem isn't still in a queue somewhere, waiting to be fixed.
Best of luck. Sorry you're going through this.
