I have a contract to do my patio and path the front path as well. I paid deposit and then provided the Credit card to the contract to pay the full contract before work. Then I was out of country. When I came back, I found out the contractor charged the full amount the second time without deduct the deposit. He said he refund me back but never did. He also said the build new steps was not part of the contract and he need to charge me on it. I asked him how much and he never give me a quote anyway. Build a step when add a patio is stand process to comply with building code. Now he is charging me at least double amount of the price. If I knew this is the price before, I won't do it. Now he threaten me will put a lien on my house and I still have not get a written invoice. What right I have and how can I protect myself. Thanks Roxanne
