Hello,
It is possible to delete your account and restart the game by pressing the "Delete your account" button in
the account settings page. However, your account will not be deleted immediately. There will be a cooldown period in case you change your mind.
NOTE: Deleting an account is permanent and cannot be undone.
However, there are ways to get your account out of debt without deleting it.
This thread outlines several of those methods.
I hope this helps, but if you require any additional assistance, please feel free to ask.
