Google doesn’t provide refunds for most Subscribe with Google purchases unless (1) they are faulty; (2) they do not match their stated benefits on the Subscribe with Google interface; or (3) if you have a Right of Withdrawal as described in the Subscribe with Google Additional Terms of Service.
Tip: If you don’t take reasonable steps to protect your account from unwanted purchases – for example, you provided your account or payment details to someone else or didn’t protect your account with authentication – we usually can’t issue a refund.
