Internet Issues, No Ticket Update, and Sales instead of Solutions

I have been having frequent issues with my internet over the past summer. I believe it has to do with some damaged cable pedestals in my development. I requested support on 06/13 and was told it would be addressed by 06/20. Since then I received several updates saying it will take longer than expected, but then did not receive any update afterwards. I tried to reach out as it tends to appear more frequently when it gets hot out, so has been cutting out multiple times during this heat wave. When I tried using support all I got was apologies and trying to sell me cheaper internet. When supposedly connected with the "tech team" it was more of the same. I asked when I could expect this to be addressed and they gave me a specific date and time, like they were going to send a tech to my home. When I asked if this was the case, I was just told that I needed to confirm the date and did not receive an answer.

I have done all of the troubleshooting, reset my modem, tightened my coaxes, etc. This has nothing to do with my home or connections there. I've been pulling my modem's event logs and it showed multiple T3 timeout and ranging request failures, loss of sync errors, and a 'TCS fail on all upstream channels' event. Since that's every upstream channel failing at once, that points to something on the plant side rather than my modem or connection issues.

My ticket number is [edit: PII]. What can I do to have this addressed, and please no more messages about how you can lower my bill.
