Nationwide Building Society has published a report highlighting some of the least acceptable practices in the financial services industry.

At a time when financial organisations are making record profits, Nationwide believes the industry should act with a greater degree of responsibility.

According to Nationwide, 84 per cent of consumers believe it is not acceptable for financial firms to attract customers with products offering competitive rates but make these less competitive after time.

A further 88 per cent feel it's unacceptable for financial service providers to offer their best deals to new customers and not to existing customers.

Stuart Bernau, above, the executive director of Nationwide, said: "Some providers continue to offer poor value to their customers and our research shows just how dissatisfied people feel."
