Please help me with support ticket that no one is responding to

A technician has visited my home on multiple occasions due sporadic internet outages.  Each time they state that they only handle the interior and that they need to open a ticket as I  have a serious problem that a higher-level outdoor technician needs to fix related to the signal coming into my house.  This most recent visit on 7/15/2025, he said that he coded the escalation as an emergency (I work from home) and that someone should be out in 5-7 hours because of how he coded it.  EIGHT DAYS LATER I HAVE HAD NO ONE COME OUT!  My internet goes down randomly for 3-5 hours at a time.  (Yep - down again right now!) I pay way to much for (1) unreliable service and (2) being completely ignored for my issues.  The form the last technician provided me had a "30 day local support number".  I have left multiple messages and received no response.  How can I be connected with someone who wants to solve the problem?
