You can restore a deleted character on the website.

I see but I don't have any points or coins to restore my character.

As far as I know it's free for first 24 hours. If it's not available for free then you will have to get those points or coins. Characters don't get deleted themselves. If you did not delete it then someone else knew your password and did it.

You had to make a ticket regarding your issue. If you are seeking support in how it might have been deleted, then well, your answer is ; it can only be deleted manually.

Making a ticket wouldn't help. We don't restore characters that were deleted beyond offering the Restoration tool that people already pointed out.
