Complaints are accepted only for image captchas. Your complaint will be checked by 5 workers, 4 of them must confirm it. Only then you get full refund. If you have less than 90% mistakes confirmation ratio, your reports will be ignored.
Why 90%? Your reports must be very precise and you must be 100% sure that they are correct. You can't just report every other captcha, you must code your software with strict testing standards and must be sure that target website does not detect you some other way.
Please note that it's not possible to reset confirmation statistics.
