Very quick, efficient and courteous customer service. My elderly mother subscribed to this service and couldn't remember why. I explained the situation via emails with Customer Support and they refunded the annual subscription fee after I verified a few details. I really appreciated their understanding and quick response. Now...I have to go unplug my mom's computer. :-)
