Henry Ejdelbaum, of accountants the AIMS Partnership, which has protested about the numbers to Ofcom and the Department of Trade and Industry, said: 'The bottom line is that there is no apparent reason why anyone should choose to offer an 0870 number when dealing with customers except to make money. The use of 0870 numbers by public services, for which we already pay an ever-increasing amount of tax, is invidious.'
