They owed me several BTC worth of rakeback last year. I opened the ticket in september 2015, they denied it for a couple months then ignored me for a couple months before finally giving me my 3BTC and status points in March 2016. They want you to get frustrated and give up. They don't want you to tell other players about it.

Me too, in last year, I found my points are too less. I found they owe me lossback of my every lost bet, they said: your total gain/loss here is positive, means you earn our money, we don't offer your loss back, is this logical?
If people lost money 1 btc and they gave your loss back and you win/lose money many times, how to count? LOL, also they owe me poker rake 
Lossback is aggregate lossback. Meaning if you're up 1000 chips and you lose 20 chips the next day, you will not receive lossback. I doubt they owe you poker rake or poker points. I have 630 players on my rakeback program, most of which are rakeback pro's yet none have complained about owed VIP rakeback. And the one's that have complained, the system ended up crediting them their rakeback a day or two later because it isn't guaranteed that you get your VIP rakeback the next day.
There's so much FUD in this thread.
