Recently, I've been getting a couple of messages a day from SMS.ac on my mobile phone, just random messages. And I am getting charged premuim SMS fee ($0.50 per message) from verizon for these stupid messages. I am kicking myself for having fallen into the SMS.ac trap by signing up on their website using my mobile number (although I am glad I did not give away my msn userID and password, unlike some of my idiot friends who did and have sent hundreds of spam to their contacts). I am sure many others have been getting these random messages and are unnecessarily being charged for it. Has anyone found a way to STOP getting these messages?
