I made the mistake of subscribing to a year subscription with annual price due at sign on. I only wanted to test the site and see if it was right for me. I noticed within a few hours what I had done when I checked my banking account. I got online with their live chat support. I talked to someone named *** and within 5 minutes, *** had fixed my account to only a month subscription, refunded me all my money minus the monthly subscription. My mistake, *** fixed immediately and was so nice and helpful. ***** customer support!
