I recently had a paving job done in the back of my house (Oct. 2012). At the time, the contractor asked me to leave the garage door open until the cement dried. He came the next day asking for a check, which I left for him while I went to work. Upon returning home, I discovered that the garage door would no longer lock, because the cement through the door off line, so that the lock would no longer engage. I called the contractor several time and he keeps assuring me that he would return to fix it. It has been a month, and he has still not returned. Keeps giving excuses. What are my options?
