Delete My Kiss Kiss Account Permanently and Unlink My Gmail

I want to permanently delete my Kiss Kiss game account. I use a guest account with my Gmail connected and my in‑game name is “AkKu”. I have been trying for a few months to delete my account and I emailed your support team, but I only received a generic answer and my account is still active. I do not want to use the game anymore. I kindly ask you to: 1) Permanently delete my Kiss Kiss account and all data, 2) Unlink my Gmail from the game, 3) Send me a confirmation that my account has been deleted. Please complete this as soon as possible.
