The Department may use in-house staff or one or more outside agencies to handle collection agency work. An outside collection agency will be permitted to add its fees to the Customer's delinquency. Once a Customer's account is turned over to such an agency a Customer must pay to the agency the entire delinquency and all agency fees and charges. Attempts to avoid the agency's fees by submitting payment only for the utility charges to the Department will not be permitted and may result in the outstanding agency fees and any related interest or penalties being added to the Customer's account or another account consistent with these Rules and Regulations.
