I cannot agree with the expensive unlocking service that is different from the advertisement.
Housing Mail order
I could not enter the house as I left the house without a key. I called a business to open the door using my smartphone. The business looked at the door and said, “We need to use a special key and special technology.” I was then charged a large amount. It was quite different from the description of online advertising. I can’t accept this.
Compare the price list posted on the Internet with the details of the charges listed on the invoice, and have the business explain again. If you are still not convinced, it will be negotiated.
