I guess it is related to their current migration to Betcoin so they might be a bit busy at the moment, and perhaps he can try to contact betcoin as well about the issue.
The user have created a scam accusation here:
Playbetr.com steals even the deposit.Playbetr representative has made a response in the thread.
By the way, will Playbetr close the website down once the migration is completed or playbetr will remain alive?
I don't think so, but I have some doubts about it. They have discontinued the signature campaign here, OP has stopped giving updates in this thread. Now they are trying to migrate user account on Betcoin.ag from Playbetr. Maybe they will make some major update on Playbetr.
