Alert for door-to-door sales of water heaters, distribution boards, roof repairs, etc.

When I was told to "check for free" on the phone or visit, when I gave it to the house, I was worried that "it is dangerous if I do not do construction" or "the exchange time specified by law has passed." I was forced to make a contract. I have received a consultation.
Let's not easily respond to businesses soliciting "check for free" etc. Also, do not only give the explanation of the business operator, but refuse any unnecessary contracts.
Please send consultation about such contract trouble to Yokohama-shi consumer life synthesis center (outside site).
