My younger brother is 13 years old and he did something similar. I added an extra line on my cell phone contract, and he did very well with it for a few months. Last month I received my cell phone bill, and it was a little over $250. I called U.S. Cellular to find out what made my bill so high, and it was from "interactive text messaging," you know, the numbers on tv that you text for horoscopes and such. They were not able to take all the charges off the bill, but they were able to give paid credits worth half of the extra charges because he is a minor. I did not ask them to do this as I understand that the irresponsibility of a 13 year old boy is not their problem. But, they were nice enough to do it anyway. Needless to say, my little brother is mowing lawns and doing odd jobs around the house to make up for the money my father sent me to pay the bill. There is no reason to blame the company for what your son did. I don't know where you live, but in most places, fast food restaurants will hire children at ages 14 and 15. I suggest that your son learn some personal responsibility and be held accountable for his actions. As an adult if he had made those calls he would be responsible to pay for them, being 15 years old should not get him "off the hook."
