I have similar bad experience. They did not provide the service as agreement. I have to keep calling them for months. They also refuse to fix the defect.

Used this company in August. waited a week to park the cars in the driveway. Now I have ruts in the driveway that they are refusing to fix. Call the company number states " Mailbox is Full. " Keep telling me they are gonna fix it. But never do anything. They want to put a sealer on it and not fix the ruts first. I replaced a driveway with ruts, and didn't pay for a new driveway with ruts. Avoid and look other places.
