Sadly no. We do not at this time have any available backups for free hosting.
Though since your database should still be intact, all you need to do is re-upload the wordpress files and set the config to match the already installed database. Unfortunately anything you uploaded, such as images for the posts, would be lost so you'd need to re-upload those as well and re-add them to the posts (otherwise you'd need to look at the image path and name for each of them and recreate the whole structure manually).
