Can a company charge you for services never requested or received?
No. A company cannot bill you for services you did not request nor receive. If they could, imagine how many people would just randomly get bills in their mail. Ignore them. They don't have a contract or agreement with you and can't do anything other than make noise. If they get aggressive or don't stop requesting money, hire an attorney and it will be taken care of.
