The only good thing I can say is that they set the fence posts straight. Everything else was a disappointment. All posts heaved over winter because they were not deep enough, and were poorly installed. They didn't bother tidying up, and left excess dirt from postholes where it lay (took me a day with a wheel barrow to remove it myself).
The job was done as quickly and cheaply as possible - bare minimum in every respect. Do yourself a favor and find a reputable, registered company who care about customer service.
