You advertised unlimited for $36 dollars and I was charged 60 What is wrong. I request a refund

Hello Henry,
Thank you for your question about the subscription price. It is a bug. For credit cards, the charge didn't reflect the sale price, and we are releasing a fix tonight for it. We regret not releasing it before you got to it.
If you can give us a PayPal address, we'd like to send a payment. In addition to a refund of $24, we will also extend the subscription six more months. Is this acceptable?

Sure!
