The situation with the bonus on deposit

Just want I’m sorry for my English translation was made ​​online translator.
I would start with the fact that the problem I was trying to solve with his manager but was unable to get his answers to their questions, so I want to apply to the community CAP.
About six months ago I had a player at the casino who is actively started to play. My partner percentage is 40%. Initially statistics were more menie truthful, I received my salary. But later started a mess.
The player began to receive bonuses on their deposits at a rate of 100% then 150% and now its bonuses on deposit is 200%. Based on the statistics, I noticed that 40% of the bonus on a deposit I have deducted from my profit, but later, when a player loses their deposit and bonus, this amount is not returned to my profit.

For example, I would like to show the statistics for early November 2010, when a player has not yet received big bonuses (I do not know why, but data on the bonuses in the statistics, you can view only the last 2 months, so an empty column with bonuses):

And now, for completeness, I would like to show the statistics for the last 3 months, when the player began to receive substantial bonuses on their deposits.
January 2011 (with bonus column is empty, but they were):

February 2011 (the player will get a bonus of 150%, it can be seen from the column):

March 2011 (the player gets bonuses often you will want 200%):

As you can see from the statistics for February and March 2011, because that only is there data on player bonuses, 40% of each bonus is deducted from Top Level Revenue and later, when a player loses will not be returned.
Mathematically, goes as follows: a player makes a deposit, he is given a bonus of 200%, 40% of the bonus is deducted from my profit. When a player loses his deposit, 40% of the deposit is added to my profit, but that sum bonus equal to 200% of the deposit. Therefore, it turns out that my profit will be negative value.
Based on the statistics, since 2011 a player has deposit amount: $ 17,266.76. My partner earnings amounted to $ 800 for January and February, and March is $ -2443.13
Clarify: This is one player who plays in a casino brand, owned by EP.
Please explain the situation.
