Xcel refuses to investigate suspicious charges

Our bill more than doubled in November-December. When we called Customer Service, they said that we were billed for the actual usage and that they could not provide a credit. They insisted a technician come out to check the meter, to which he found nothing. Still haven’t received a credit because they refuse to acknowledge that their reading was incorrect or that there was a billing error.

It also occurred during the month that they switched the tiering system used to charge our account. They refuse to investigate any further.
