I had a battle with Verizon Wireless today over the same thing. I received 4 text messages for which I was billed 60-cents and was billed $9.95 for ONE text that I sent. I called Verizon to disCUSS it and the man told me that an online game provider had somehow obtained my cell phone number and sent a text message that said, "To sign up for these games please reply to this message and you will be billed $9.95 per month." I didn't read their message but did open one so I could send them a STOP message. Being ignorant of their scheme and after having received 4 messages with the same title, within about 45 minutes, I sent a not so polite text saying remove me from your text message list." The man said my reply had authorized them to bill me $9.95 per month through Verizon to receive their games. I have absolutely no idea what they were. He wanted me to think Verizon could do nothing about it because I had authorized the charges. I told him I could and I would do something about it by canceling my contract with Verizon. He suddenly had a stroke of genius and removed the charges and placed a block on the company charging me for games.
