Hello Mary,
Thank you for your question about your extra payment. The short answer is: PowerSnipe will refund you if you e-mail them. It was surely an oversight. We also sent an email of our own to PowerSnipe on your behalf.
We know that they intended to cancel their subscriptions some time ago, but this one appears to have gone unnoticed.
Also make sure to cancel the subscription at PayPal by visiting the payment page at PayPal. Please do not dispute the charge, because we know that they will refund it.
As for our payment, you paid us $12.99 for a month and this subscription was canceled by you, so you will not see any further payments.
Please let us know when this matter has been resolved to your satisfaction.
