Comdata Network Inc., overbilled the Tennessee Valley Authority by more than $1 million with duplicate invoices and charges on credit cards used by TVA employees to buy fuel over a 21-month period, a TVA audit shows.
In a review of Comdata's work for TVA released Monday, TVA's Office of Inspector General claims that Comdata submitted $846,022 in duplicate invoices, merchants made duplicate charges on another $83,271 and state fuel taxes were paid although not required on another $106,174 of TVA fuel during fiscal 2012 and 2013.
"The contractor was to provide TVA with a MasterCard platform and issue fuel cards to TVA personnel to purchase fuel, vehicle fluids, and car washes for TVA-related business," TVA Inspector General Richard Moore said in a report summary released Monday. "In summary, the OIG determined TVA was overbilled $1,044,302."
In response, Comdata said it should be reimbursed by TVA for $192,042 in state taxes stripped from invoices which TVA was liable or the contractor could not claim in some states.
