(Telecompaper) Ofcom said Vodafone must pay a total of GBP 4.62 million for breaching consumer protection rules in a "serious and sustained" manner. The UK regulator said the imposition follows the completion of two investigations, resulting in two penalties. In the first investigation, Ofcom found that Vodafone took money from pay-as-you go customers, without providing a service in return. This occurred when the operator moved customers to a new billing service. In the second investigation, Ofcom found flaws in Vodafone's complaints handling procedure, including mis-selling and inaccurate billing.
