Can the gas company obligate me to pay a gas bill that was in my roomates name. We had an arrangement whereby I was responsible for some of the utilities and he was responsible for the gas bill. When he left, he closed his account. I called to have the gas put in my name and they told me I would have to pay his bill. I don't live in the same place anymore, but they are still trying to tack his bill on mine. I have tried to deal with the public utility commission but they say since I used the gas too, I have to pay. How can I be obligated to pay someone else's debt?
