Install issue

I get customer service rep after customer service rep promising me this and that and still no internet, no box put in, still not able to work! What do I have to do to get this completed. 

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

They was out here putting in new lines and posted a Xfinity sign by the mailboxes, so I called and I understand that they just got lines ran, and had to run the lines bury them to my property etc. I have been absolutely nothing but understanding and have had total patience with everyone involved ask the customer service reps. And I just am at another stand still bc I haven't been told when they are coming to install the new box across the street. Like am I going to have to wait couple more months, I do not get any updates as what's happening. I have to call and set up appts myself for what needs to be done. And everytime I call I have to go thru the whole story it's just getting old. Like I said I started this end of August and have been trying to switch my phone also but can't til internet is installed. 

No it's new to our area, we'll they put all the lines on the main road and had to run lines from down road. But they were advertising that xfinity was available to my property. And that's why I was patient with them running lines and stuff but since August is little long
