Unhappy customer

On December 31, during my chat with your agent (see attached screenshots), I was told: ‘Since the services were moved today, the activation process usually takes up to 24 hours. Everything should be ready by tomorrow.’ Three days have now passed since that December 31 conversation and the TV boxes are still not activated, so we have no working TV service despite being billed for it.[xfinity]
I contacted support again and was told the soonest available technician is 10 days from now. This is not acceptable for a non‑working service that I am already paying for.
In light of the assurances in the attached December 31 chat and the ongoing lack of service, I am requesting that you:
1. Immediately escalate this to a supervisor/retention so that a technician can be scheduled much sooner (same‑day/next‑day or via a cancellation slot); and
2. Apply appropriate bill credits for each day since December 31 that the service has not worked.
Please confirm in writing that this has been escalated, provide the earliest possible appointment date, and specify the credit that will be applied.”
