BOGUS callers who are telephoning a water company’s customers have been branded “unscrupulous”.

Hatfield-based Veolia Water has issued a warning to residents to be extra vigilant after reports across the region about conmen claiming to be from the firm.

The callers are offering discounts to customers if they pay their bill in full over the phone using a credit card.

Vincent Muldoon, director of customer relations at the Tamblin Way company, said: “We are very concerned about these unscrupulous people who try to defraud our customers by obtaining their bank details.

“Employees of Veolia Water would never cold call our customers and offer them a discount for payment, and we urge people to be vigilant when they give out personal details over the telephone.”

Mr Muldoon said any resident who had received a call like this who thinks they may have been a victim of crime should contact their bank and/or credit card company as soon as possible, and report the incident to police.

He added: “If there is any doubt, do not continue with the conversation, put the phone down and contact our customer contact centre on 0845 782 3333 and the police.”

Veolia Water serves 3.2 million customers in a supply area that covers 3,700 sq km.
