Since you have already downloaded the plugin twice before the refund, I will consider this a 'giveaway' due to your purchase accident.
However, please be noted: as you are no longer a valid license holder, I will provide ABSOLUTELY NO TECHNICAL SUPPORT if you encounter any issues while using my plugin. You are the first and the last person to receive this kind of treatment for such an 'accident'.
I have officially updated my Terms of Use to strictly prohibit refunds after a download is detected to ensure this never happens again. Good luck with your turn-based RPG.
