People are more unhappy with postal services than with banks, broadband providers and mobile phone companies, according to a Which? survey.

Junk mail leads the list of concerns among the 1,029 people surveyed followed by post office closures, missing post and long queues. Of the 1,029 people surveyed, 16% said they were 'very satisfied' with Royal Mail; for Post Office services it was 28%.

Which? Editor Neil Fowler said: "In most cases, if you are unhappy with a service provider you can easily switch to another one, but postal services are the exception to this rule with a real lack of choice available. There are ways in which you can improve the service you receive, by taking steps to reduce junk mail and claiming compensation where applicable."

Royal Mail said its own research consistently found about 92% of people satisfied with its services.
