last night I had 288.000+ chips, This morning I have 35.000 what happened.
Best you can do is send an email to email@example.com. or use the ? in the header to send it to the staff.
There they can see into your bankroll and see what happened. (dont forget to mention the date)
So the missing 250K was the buy-in to a tourney. Not sure how you managed to be registered for it, but we can refund your buy-in amount - no problem.
