A Japanese man was arrested for allegedly calling a phone company — a whopping 24,000 times — to complain to them about his contract, police said.

Akitoshi Okamoto, 71, was taken into custody last week for apparently inundating KDDI Corporation's customer service department with toll-free phone calls over an eight-day period.
