I received a letter from the city stating that a permit was never pulled for the patio cover. I called the contractor and he said it was approved. I went to city hall and they told me that the contractor was given revisions that had to be made to the patio cover, before being built. I called contractor and he said he was going to take care of it. A week and a half later, he hasn't followed up on the permit and he is not returning my phone calls. He did send me a refund for the permit, but the damage is done. He built the patio cover without a permit and he told me that it was approved. What can I do?
