If you were subscribed to a paid service without agreeing to it you might be able to receive compensation. Verizon and Sprint recently got in trouble for allowing unauthorized third-party charges. As a result of this, Sprint and Verizon agreed to provide a free service that blocks third party charges. I'd I'd suggest calling up your carrier, and threatening to report them to the FCC if they prove to be unhelpful. You might also be able to receive compensation.
