Postegro Subscription Purchased via Telegram Link – No Service Provided

I purchased a Postegro subscription through a link on Telegram and entered my credit card details. However, the service isn’t working, as it fails to display any profiles as promised. I want to cancel this subscription immediately to avoid any automatic renewals and will be securing my card to prevent further charges.
Please provide guidance on canceling the subscription, as I have received no support or functionality from this purchase.
