They don’t do anything right

We have had Comcast for three weeks now. On July 12th they were supposed to be at the house between 1-3. I had family plans at 6pm. At 3, no one had shown up and no one had called to let us know what was happening. So I called them. They told me the tech was running late and would call in about an hour to give an eta. I asked them why exactly I was never notified and they said they were not sure what number to call. I said “perhaps you should have called the number on file I just gave you to pull up my account”. So they are already either not very smart, or are just making up lies to cover their butts. They finally show up around 5:15. They had to put a new line in and told us someone would be out to bury the line in a few days. A week and a half goes by and no one comes. The cord is orange and goes across our drive way so it is an eye sore. So we call back and they “schedule” it for two days later. And no one shows. So we call the next day. They schedule it for two days later. At this point it has been three weeks and we need to mow our yard. My husband runs over the cord and cuts it. Which is on us, but we call and they specifically tell us that the tech coming out will fix it and bury it. But of course no one shows AGAIN! So now we are without all of our services, and the cord is still there which HOA has already made a comment about. What exactly do we need to do for them to do their jobs?!? Don’t recommend this company or their customer service.
