U.K. telecommunications regulator Ofcom said it was investigating customer complaints against Vodafone Group Plc, part of a recent spate of inquiries into British mobile-phone operators.
The inquiry was related to both billing and complaint handling, Ofcom said on its Website on June 11.
“We are always disappointed when customers have issues with our service and we do not resolve them effectively first time,”Vodafone said in an e-mailed statement. “Our customer services teams aim to provide our customers with a great service every time but we are clearly not there yet.”
The company, based in Newbury, England, was improving its network, training and billing, spokesman Simon Gordon said.
Vodafone shares, trading ex-dividend, were down 3 percent to 236.80 pence at 1:09 p.m. in London, giving the second-largest mobile-phone company a market value of 62.8 billion pounds.
