Today we launch a major new series investigating the parlous state of customer service in Britain. We start on telecoms companies, which, despite being in the communications business, generate more complaints than any other industry. Britain's internet and phone companies show a shameful disregard for their customers - leaving 4.1 million people unhappy with their service every year. Official figures show that an incredible 3.3 million customers have been left waiting three months or more for their phone or broadband provider to resolve a problem.
