The UK’s Vodafone Group is planning a new year customer services offensive in Germany, aiming to raise its mobile revenues and increase its subscriber base for DSL internet access, a company spokesman has told Dow Jones Newswires. He said a key part of the drive are Vodafone shops, whose number should rise to 2,000 in the next one to two years from 1,600 at present. Shops are a good place to give customers advice and raise interest for the use of mobile data services, the spokesman said. Vodafone markets DSL lines in Germany both on its own and together with Arcor, in which it has a 73.6% stake. Between them, they claimed around 2.34 million customers at the end of September 2007, representing a broadband market share of 13.6%. Vodafone is looking to increase its slice to 20%. The spokesman declined to specify the investment in the customer service offensive but said costs will remain stable.
