Issue with signal on Channel 516 TV5MONDE

For the last several days video and audio have been breaking up on channel 516, TV5MONDE. All other channels checked are fine. The issue is most likely with bandwidth on the uplink or downlink in the communications channel between TV5MONDE and the Cox infrastructure. Pursuing the issue through the chat bot and a human agent was unproductive. They just wanted to go down the checklist of restarting and power cycling our equipment and finally wanting to send a technician to our house, which was a total waste of time and effort. This problem with a single channel is clearly a Cox system issue and not local to our equipment. I asked that the problem be escalated through the management chain but have not heard anything back and the problem persists. I would like to hear from others who watch TV5MONDE and any suggestions as to how to get Cox to correct the issue.
