A residential customer may advise a utility by written notice, by telephone, by email, or in person that utility charges are in dispute. If a residential customer disputes the amount of utility charges, the residential customer shall pay the utility an amount equal to that part of the utility charges not in dispute. The amount not in dispute shall be mutually determined by the parties. Failure of a residential customer to pay a utility the nondisputed amount of utility charges shall constitute a waiver of the residential customer's right to continued service.
