I recently signed up and paid for a three month membership.
Toward the end of the membership term I canceled my membership and received a confirmation of the termination.
One month later my credit card was charged for another three months at the full membership price.
I called and was on the phone for at least one hour with a customer service rep before I was able to speak to a supervisor regarding a refund.
I had to demand this request and when I did speak to a supervisor I was only offered a partial refund which was only a fraction of the amount they charged my card.
