Even I kicked from telegram chats.
Its nothing new and most of time they try to keep victims far from their telegram channel. Actually its a cheap attempt to hide their fraudulent activities from their community rather than resolving the issue. I hope they will provide explanation here soon which can bring a proper solution. Lets see what they got for us.
Keep patience and wait for their response.
If they want to remain in business they will surely resolve this issue. If they did not respond or resolve it, they will lose lot of customers from this bitcointalk platform. It is in their interest to pay the OP and regain their trust else no one will play at their site. Also 0.5 bitcoin should not be a big amount for a gambling house.
