Disconnection Threats with No Remedy Possible

Xcel sent me a final notice for disconnection because their contractor was not able to access my meter for smart meter replacement. The instructions to avoid disconnection are to schedule an appointment directly with their contractor. The issue is that the contractor cannot be contacted and all you hear when calling is that the voice mailbox of who you are trying to reach has not been set up. If Xcel is going to threaten to shut power off, they should ensure the remedy is actually possible. I have no control over an incompetent contractor.
