Ожидаю ответа на свою жалобу.

Good evening! I have filed a complaint and am waiting for a response to what I have told you.

Καλησπέρα σας ! Έχω κάνει καταγγελία και περιμένω απάντηση σε αυτά που σας έχω πει

Yes, that's right. There's a timer in the top right corner that shows how long the page has to respond. I saw that there are still two days left, so you'll have to wait a little longer for Petra. There are quite a few complaints, so it's not possible to get to everyone right away, but don't worry, you'll definitely get a response.
