From the video on the YouTube channel "Takku TV Reidio"

On March 13, 2022, popular YouTuber Takku posted a video on his channel "Takku TV Redio" saying, "I kept paying utility bills for strangers." Revealed. Explains problems with cancellation. [Video] The full story of the mysterious utility bill ■ "It was a record that you canceled the utility bill two months after you left the house." It's the man who kept paying for it, huh?" He said, "I've been paying for it all the time. It's a mystery, isn't it?" It took about five hours to make phone calls. Mr. Takku had canceled and moved out of his rental apartment in Fukuoka, where he had been unable to return home due to the effects of the new coronavirus. However, it is said that the bill of 8000 yen for utility bills for the apartment was delivered to the house where he is currently living. It is hidden whether it is electricity, gas, or water. When Takku-san moved out, he once restarted the electricity, gas, and water supply. I feel like I asked for it, so maybe that's why they billed me all at once." He said, "I thought it was a little expensive, but I paid normally." However, two months later, Mr. Takku received a phone call from a utility bill collection company saying, "You are two months behind on your bills." He ended the call by saying, "I don't live there anymore," but then the same company called me again, saying, "You're still being used." Mr. Takku was told that the charges for the two months on the bill were 2,400 yen and 4,500 yen, respectively. However, it is said that it was "the bill for the month when I am completely moving out." Thinking it strange, Takku-san phoned the original contractor to confirm, and found that "it was recorded that the utility bills had been canceled two months after moving out." However, in the first place, I 'closed the faucet, closed the main valve for gas, and turned off the breaker for electricity,' before moving out, so I just can't understand.
