I can feel your situation as I have almost same experience at Stake.com. But you shouldn't address the game as rigged as you can verify the results of the game on other website. I'm losing around $10 for every $1k wager on the in-house games of Stake since last few months. Seems like the house edge has become 10% for me. We have to accept it as the house edge always wins if we play for a long time.
The same happened for me long time ago when I won several thousands dollar in a week, I lost it all back in the following week.
Of course I did not cry or try to accuse the site of doing something unfair to my account, because I could win it back in the following month.
What I can say is that it was pure lucky and unlucky moment in gambling, some time we win and some other time we lose although we are aware that most of the time we will lose due to house edge.
Lesson learned is that we should know when to start, when to rest or when to stop and when to restart a new session.
