The Texas Department of Transportation (TxDOT) in the US has levied a fine of $177,000 on Xerox, which was awarded a contract to operate toll roads throughout the state.

In September 2013, TxDOT selected Xerox to provide customer service and toll operations to the state of Texas over the next five years in a $100m contract.

The contract includes handling customer service and the TxTag website, but since Xerox took over last year, the customers have complained about various billing problems, issues with the website and long wait times when trying to connect on the phone, according to kxan.

"Xerox established a new customer service operation in Austin, Texas, to process more than eight million monthly toll transactions while managing more than 750,000 accounts."

TxDOT has previously promised the situations plaguing the TxTag billing process was getting better and claimed that the issue was fixed in September, but still received complaints from customers saying that they are unable to reach representatives on the phone.

Customers also said that the website was not working properly, while some others said they are receiving incorrect bills.

Further to the contract awarded in September, Xerox established a new customer service operation in Austin, Texas, to process more than eight million monthly toll transactions while managing more than 750,000 accounts.

Transaction processing, licence plate image review, invoicing, collections, transponder sales and management were included in the customer service centre operations.

The company also provided roadway assistance by assuming responsibility for the physical maintenance of the toll plaza buildings and continuing the courtesy patrol on the TxDOT toll roads in Austin.
