Okay guys, I will tell you how to get your channels back:
1. You must remember the username of the channel
2. Search for it in global search from many accounts
3. Search for it in your main account
4. Telegram will give the username back to the channel
NEVER change the username once you get it back. You will never be able to get the original one back if you attempt to do so E.g., @hello gets banned, but you get it back. You change it to @hello1, but now you want @hello back. It will remain banned
The recovered channel will be only accessible via global search, and you can click on it only if you previously searched for it before. E.g. try with @botlist
