Refund Please?

Hello,

I recently tried the 7-day trial, but I had no idea that I would be charged 49 dollars for the yearly subscription once the trial ended. My debit card wasn't working properly, so I used my dad's PayPal, and he is quite upset about the transaction. Is there any way I can receive a refund, I do not want a yearly subscription. I have already canceled the subscription, but there is no phone number to ask for a refund.
