Signed up for the trial period and neglected to cancel in time. Asked for a refund and got the same canned response as other people and had no initial reply to my request for a full refund. After filing a dispute with PayPal I got a reply from them saying they would give a full refund but couldn't when the dispute in Paypal was open.
That last bit is simply not the case. Paypal states on their dispute page that they do not advise cancelling a dispute UNTIL the refund is issued. I've replied with this information to them and am awaiting any sort of refund.
