What do you think about the topic? I have tried to find someone to exchange messages with several times here, and with other resources too, but, unfortunately, with no luck. Sometimes they answered to me that they have no possibilities to answer so many requests to them from those who want to study English, sometimes my suggestions were left unanswered. I am a bit discouraged.
Thanks for your opinions.
It is possible and I have met many wonderful people here but there are some things to consider.
1. Native English speakers are indeed flooded with language exchange requests because the whole world is learning their language but they (generally speaking) don't learn so many languages. So native speakers of not so frequently learnt languages might have a harder time, finding native English speakers to practise with.
2. Therefore it's advisable also to practise with fellow English learners who have the same or a higher level.
3. If aiming for native English speakers, you should look for native English speakers who are learning your language, so you have something to offer in return.
4. Most people don't reply to simple "hi" messages. Best is to introduce yourself and describe the kind of exchange you're interested in.
5. Here on italki it's best to take part in discussions, correct notebook entries in your native languages and answer questions of learners of your native language. This way, you get noticed by other users as a reliable partner.
6. In my opinion, it's best, not to look just for native speakers of your target language, but for possible friends. When the personalities click, then it's much easier to find topics to talk about and keep the conversation going.
7. And very important: Before contacting other users, you should read their profile. I get so many requests and when I ask if they read my profile, the answer is in most cases "no" and then I'm not interested in that person anymore. If they can't be bothered to take a minute to read my profile...
Anyway, this is general advice, especially for new users on italki, not just for Alex.
You can try looking for language exchange partners like you have done including many other people, but there is no guarantee that they will be reliable, as you have already found.
Or you could enlist the services of a tutor then you will at least be guaranteed that there will be someone to help you like I myself and many other students have found.
Obviously, there are pros and cons to both decisions. You have to decide how important improving your language level is to you.
Good luck on your language journey.
You're welcome. Не за что!
