As someone who does it and someone who has sites in other languages than english, I can’t recommend these services for websites of another language.
People who do submission follow their own list of directories.
You can’t lose anything, but any serious directory will decline you. Those where you’re automatically added aren’t appreciated by Google algorythm.. so while you won’t lose anything, I don’t think you’d necessarily get your money’s worth.
You have to look for someone who does submissions specifically for your language. But if it’s not english, it’s always expensive
