When I enter my page URL http://korydor.in.ua/reviews/1507-vzyat-na-karandash to https://developers.facebook.com/tools/debug/ I can see that Canonical URL is pointing to some random ya.ru domain.
How to get in touch with Facebook dev team to fix that ?
This page has relevant metadata information, it is not a case of the problem
meta property="og:url" content="http://korydor.in.ua/reviews/1507-vzyat-na-karandash"
Further down that same page it explains why this is happening, screenshot attached
Your site is redirecting Facebook's crawler - you need to stop redirecting the crawler if you want the metadata for that URL instead of the after-redirect URL
