reports that police have arrested a 71-year-old man in Saitama for calling his cellphone company's customer service line roughly 24,000 times with a variety of questions and complaints.
According to the company, Okamoto was upset that his telephone was not able to pick up radio broadcasts and called multiple times to vent his frustrations. The police investigation is still ongoing, but they say that according to KDDI's access logs Okamoto has called them tens of thousands of times since becoming a customer of the company. In an interview, the senior citizen told police that he was the victim in this situation.
Maybe he has dementia and honestly doesn't remember he's called repeatedly.
