ProBiller.com review: Probiller subscription

I made a purchase for a trial membership and without knowing it signed up for a second trial membership. I cancelled the original membership before the trial was up but have been getting charged 34.99 for the second trail regardless of my not knowing and never using the membership. hidden memberships are apparently an ongoing theme here. On the phone with customer service i was denied a refund initially and offered a "compensation" of a free membership. it took 20 minutes of haggling and researching while on the phone to get ahold of their refund policy. I asked to talk with a supervisor and was denied. They said that they do have supervisors, but that their supervisors do not take calls and that there is no process for case escalation. I asked for a physical address to send a letter to get in contact with someone above the customer support member.. also was denied that information. Asked for the name of the supervisor, again denied. all i was given was the customer support agents first name and extension number. i eventually recieved a partial refund of half of a month. i accepted but made it clear that the grievance had not been satisfied and that i would seek to further fight the charge.
