Problem After Problem, Where is Xfinity?

To start off I would like to say I have always given Xfinity the benefit of the doubt as the service has never really been a hassle. However that has changed and something needs to be done as the issues have built up and Xfinity is no where to be seen to help.

Problem #1 - Since transferring my service from one address to another I have had ZERO access to control my internet or the equipment because somehow my online equipment is deemed "offline" and only my old equipment that we don't use anymore is showing up for me to do anything with.

Problem #2 - The fiber cable that runs from the service box to my home still has not been buried after 3 months. A crew came about a week ago to bury it and they were here long enough to tell me they were here to bury it and then to get back in their truck and leave without burying the line.

Problem #3 - Sunday, January 5th at 10pm, our internet went out after an issue with our power that lastest at most 2 seconds. The ONU remained on with 3 green lights while the gateway has been flashing an orange light since then. I contacted a live agent the next morning after spending the night restarting and trying to troubleshoot the equipment. After going through 3 agents unsuccessfully attempting to resolve the issue, the 4th was successful and deemed the ONU as the issue and that a technician would have to fix it. I told the agent I needed this fixed  at the latest by Wednesday January 8th (today) or Xfinity would need to reimburse me for the $3,000 college courses and other long term damages caused by this issue which the agent deemed Xfinity's fault. They stated they had me set for a priority appointment today (Wednesday) between 1-3pm, I never recieved a confirmation notification and it is now an hour and a half past the latest they should have arrived and I am still without internet. My family relies on this internet for my college courses, my brother's homeschooling, and my mother's job, all of which we cannot do without the internet and effects us financially.
