3 Missed Tech Support Visits in a row

I have had 3 tech support visits scheduled since Sunday (10-12pm), Wednesday (8-10am), and Wednesday (3-5pm). Sunday was cancelled with no reason given. Both on Wednesday just never showed up. I have rescheduled a fourth visit for Thursday (1-3pm). Will anyone show up this time?

I am just trying to get clarification as to why my network drops constantly. I receive numerous messages similar to the one below:

Hi, it's Xfinity Assistant.
We've identified a network performance issue that may be affecting your Xfinity service and needs to be repaired right away. We're actively working to fix it by 05/27/2025 11:55 AM. We'll do our best to minimize disruption in the area. During this time, you could experience a service interruption at <address>. We apologize for the inconvenience and will text you when the issue is resolved.

Last week, I scheduled the tech visit because the call agent identified the following:

Agent (01:32 am): I have identified an issue with the outside wire connected to your modem outlet. I am trying to refresh the signal for you. If the issue persists after the refresh, we will send a technician to your home to check the wire and fix it.

Agent (01:38 am): I have checked, and the signal is complete now. However, there is still an issue with the outside wire, so we need to send a technician to take a closer look and fix it.

Agent (01:39 am): let me check the soonest slot for you

Agent (01:40 am): I am getting the soonest slot for you :- Sun Jun 01, 2025 from 10:00 AM - 12:00 PM EDT

What can be done to be sure appointments are kept? I cannot keep taking time off to sit around and wait for no one to show up.

Since the disruptions were so numerous, I was forced to get a second backup internet. Should I just keep that and cancel Comcast? Any assistance would be most appreciated.

- kinda frustrated ;)
