Excellent Customer Support I received quick email responses from costumer support and very fair and kind help - I wasn't aware of my subscription status and was billed for a full year. Because I didn't need the full year subscription, I cancelled my subscription and emailed customer support right away to let them know. I requested a refund and it was kindly granted. Mind you, I emailed them as soon as I got my billing notification from PayPal and my bank account hadn't been charged yet - but they made sure to refund me before I was charged! Many thanks to the helpful customer support worker.
