Does this company ignore customers who have no choice but to use Comcast?

Living in a condo association that only has Comcast as an available ISP besides satellite internet. I've been having issues for several months now. Finally got a human to speak to who promptly sent a technician out to see what is going on. Technician arrives, determines there IS A PROBLEM, however the issue is outside of my home and will need a special request to service. I was told the special request is usually same day, but being as its Saturday, it would most likely fall on Monday. Monday rolls by, nothing, a week rolls by.. I call and speak to a representative. They tell me they don't have any info on the request other than it was put in. But it should only be 14 days.... 21 days roll by, i reach Comcast by chat support, they say they confirm the issue and its being worked on??? and should be finished in a couple days.  That again was another week ago. I haven't seen any Comcast trucks, nor have i heard anything from support. I doubt this one specific issue would take months to fix anyway especially after the onsite tech told me it should be SAME DAY. This issue is affecting my livelihood as i work from home. Ive lost internet over 300 times SINCE i started monitoring a few months ago. I feel like im being held hostage because this is the only ISP around. If there was ANY other ISP other than satellite internet that costs hundreds of dollars a month I would have left Comcast a long time ago. Terrible response from their customer service team as usual. NOTHING is being done and im being fed lie after lie and im honestly fed up with it and wondering if there is some sort of law against being monopoly to consumers like me who just need some internet.
