Comcast Frustrations!!!!

For three weeks, the apartment development I live in in Baltimore has had intermittent-to-no service whatsoever from Comcast--no TV, no Internet, no phone. After several visits to different customers, and several neighbors talking to each other, we determined the problem was not our individual service but a problem in the complex. The technicians "bumped up" the service request to the next level, and we were assured it would be taken care of right away. *Then* we were told it would be 7-14 business days before anyone could do anything about it because they had to get permission from the county to dig up the ground (not, of course, that they actually know what the problem is!). Now they're telling us the problem is fixed, when we clearly have no service whatsoever. I called two hours ago and asked to speak to a supervisor and was assured someone would call me back right away...as you can imagine, that hasn't happened. One hand doesn't seem to know what the other is doing, nor does anyone seem to care--the other day someone told me that since I didn't have a business account (I'm a journalist and told her that I was unable to work without an Internet connection) I wasn't entitled to the same service that business account holders receive (of course, the fact that the leasing office in the complex has no service either doesn't exactly support that notion). We are beyond frustrated. If anyone has any suggestions, or if someone from Comcast is out there listening (and according to today's New York Times, you are!), please get back to me. My account number is 09519502721-06-5. Thank you!
