I'm being charged for ERROR_CAPTCHA_UNSOLVABLE


New member
Hello, I've been sending requests to solve recaptcha v2 on google pages and after submitting all the necessary tokens I get around 40% of solved captchas but a lot of ERROR_CAPTCHA_UNSAOLVABLE.
It's clearly stated in the docmentation (https://2captcha.com/2captcha-api#res_errors) that I will not be charged for captchas returning this message but it turns out that my credit is decreasing by the number of total requests (those solved and those returning ERROR_CAPTCHA_UNSOLVABLE too).

Should I send a complaint to get refund for these requests or they should be automatically not charged from your side ?

Thank you.
