Protestors fighting to keep a Lincolnshire post office open have taken their campaign to London.
The protesters want to keep their post office open
The residents of Langworth have said approaching government on the issue is like "talking to a brick wall".
About 20 people have protested at the offices of the Department for Business, Enterprise and Regulatory Reform.
The department, which is helping run a consultation on post office closures, said the network of post offices in its present form is "unsustainable".
Protester John Thornes said it seemed to be difficult to get their message across to the government, but the trip to London was an attempt to "build bridges".
"We felt that all the time it's been like talking to a brick wall - in talking to them and sending letters - we've got nowhere," he added.
The Post Office Limited insists the cuts across the UK are necessary to make the whole network viable.
Almost 50 branches across Lincolnshire are due to close or be replaced by other services as Post Office Ltd looks to cut losses.
Another round of consultation on the future of Post Offices in the east of the county is due later this year.
A Post Office Ltd spokesman said: "We are aware of the high regard in which Post Office branches and those who serve in them are held and unfortunately with any change to the Post Office network some customers will be affected."
