CT laws regarding debt settlement, debt collection

Bill payment: Can a cable company transfer another customer's bill to another customer for payment solely because that customer lives in the same house and because that that person was given authorization to change the movie channel on the account? They also cited that the person used their personal checks to pay on my account. I never co-signed on that person's contract with the cable company (I have a seperate account), however, they are holding me liable for the debt incurred by that customer by transferring that amount to my account for payment.
