I’m sorry for your loss. I would keep pressing if I were you. There is just too much at stake. I have seen similar things happening to some of my colleagues.
It’s also interesting how different is Play Store and App Store I terms of developer treatment. At least in Apple you get to talk with an actual person giving you more information and possible solutions. Google should take example.
Don’t give up yet — you never know who might read this. All the best.
