A pensioner in Japan has been arrested after making 24,000 complaint calls to his phone company and claiming they had violated his contract.
Akitoshi Okamoto, 71, was taken into custody last week after he made 411 calls to telephone operator KDDI in a single week last month.
Some media outlets have reported that he made thousands more calls from public pay phones to insult customer service staff.
Tokyo police said: 'He demanded that KDDI staff come to him to apologise for violating his contract. He also repeatedly hung up his calls immediately after placing them.'
He has been arrested on suspicion of 'fraudulent obstruction of business'.
Local police said that Okamoto was angry because his telephone couldn't pick up radio broadcasts.
He reportedly called the company 33 times a day on average.
Japan is seeing an increasing number of social problems caused by the nation's rapidly ageing population.
Old drivers frequently cause fatal car accidents and railway operators have reported a spike in passenger violence against their staff from elderly customers.
