use of the send complaint button
I like to play The Sololearn quiz. It contains huge amount of realy good questions. But sometimes I got questions with wrong (or multivariant) answers. There is the "Send complaint" button in the top right corner of the "view correct answers" page: exclamation mark which opens a submenu with items like "Incorrect spelling", "Wrong question", "Wrong Answer"... (in English, the captions maybe different). I used this button to send complaint about errors in some quiz questions. I used "Wrong answer" and used "Other" for explanation what is wrong in that quizzes. But during the game I sometimes see that wrong answer to quiz again even if I have sent the complaint about it two weeks ago. I understand that threre may be many complaints from players and moderators may be busy. But I can not see the status of my complaints and I don't know having seen them the moderator(author) or not (or maybe moderator didn't accept my complaint as wrong). Does it have any sense to send the complaints about wrong quizzes or it is just wasting of my time? P.S. I have experience in programming, I use Sololearn to check my skills before job-interview (I am seraching for a new job now) and to improve my skills in other languages.
