I see that you have upgraded your account from Premium to Economy. Upon upgrading to Economy on 29th April, the account subscription changed to Economy. Since the subscription is paid through PayPal, it is required to cancel the existing subscription manually from PayPal. Hence, the premium subscription remained active on your account and renewed again on 6th May in which changed the account subscription to Premium.

I've changed your account subscription plan to Economy now. I'm sending a refund request for the recent payment of $9.95 for Premium subscription and cancellation as well so that you'll not billed on this subscription again. Please allow 4 to 5 business days to process the refund.

Thank you!
