I am sympathetic to your problems. You seem to be at the stage where you are starting to get players, but not yet enough to balance out the variance.
It is a very frustrating stage and at this point a lot of affiliates drop out.
It’s not the programs problem, Wager Profits is a super honest program and Referback too is known to fix problems as they occur.
It’s that you don’t quite make enough money to take the punches without hurting. This is a gambling business, and there is an element of gambling in all aspects of it, including the affiliate job. At your stage, the losses hurt a lot.
Just stick to it and improve your site(s) all the time and think about what kind of player would be best for you to have, and speak to them from your site.
You will get past this phase and then you will see that it all balances out in the end.
