Can anyone fix my internet. Because the Tier 1 India guys are not doing the needful.

 I was upgraded for free to the 2000mbps service in July 2024. It has been a nightmare ever since. They had head equipment issues with 25% of the USA infrastructure providing that 2000mbps to customers. It took then 10 weeks before they got a firmware update from the vendor. I got back on the service in November 2024 and it went from 325mbps max to 1300 mbps and that are my top end tests to my modem. My modem is currently being switched out for the 3rd time since November 2024. I have had Comcast Business, line techs, area managers and countless appointments and STILL SERVICE IS TERRIBLE. Calling India Tier 1 techs is useless. They never do the needful. Can I get some real help. I currently have an escalation, but the comcast rep has been down with his service for a week now and I cannot get a hold of anyone. He must have Comcast service. I need this fixed. You want to know why Comcast has such a bad rep, because people like me are telling you that your equipment is broke and no one cares.
