I think that this project is not running anymore, because there is no latest news from Playhall and the team is also not active, is the Playhall a scam project that runs money from investor participants?
do they just make an appointment?
You have created the posts 7 days ago but the team still not responded means there is something wrong. They might have flew away by taking funds of investor.
They can be really very busy in development. Let's give them a chance.
