Hired a roofing company to repair a leaking problem. They came assessed the problem and gave me 2 different options. I signed a contract clearly stating option 1. The repair work happened and the bill for $1,712.00 was paid in full. I just received an email a couple days ago from this company requesting payment for the 2nd option that I did not authorize but they say they did. What are my rights? I feel like I'm being taken advantage of because I don't know exactly what was or was not done to my roof and I'm worried that the company will put a lien on our home for work we didn't authorize to be done.
