The queen of the high street wants to start a revolution in customer service. And she want to hear from people who are fed up with bad service to take part. Speak out about your most memorable experiences and you could appear on the show.

Apathetic floor staff, impersonal automatic phone systems, and non-existent complaints departments can make our lives hell.

"If I were to rate Britain's customer service reputation - I'd give it a failing grade. There are few brilliant brands who get it right but most days I come across inadequates posing as sales assistants who don't give a monkey's about their shoppers as long as the cash keeps rolling in. It's time to rise up and demand good customer service or take our business where it's appreciated," says Mary.

Tell Mary about your biggest bugbears when it comes to customer service and you could be selected to appear on the show as she transforms Britain's customer service industry.
