Отказ в возврате предоплаты Refusal to refund advance payment

I booked this hotel on April 26.2021 for the dates of September 05-16.2021, paid an advance payment for 2 rooms for a day (1624 UAH), clarified in advance whether it was possible to return the prepayment in which case, they answered that if we warn 7 days in advance, they will return no problem at full size. I called today, 08/26/2021.10 days before arrival and asked to return the prepayment, since there was no way to come, they flatly refused, they said that they did not return the prepayment on the website, although this is a clear violation of consumer protection law, you can return the prepayment not only 7 days, but even a day before arrival or on the day of arrival. In general, I have now prepared a letter to the owner of the hotel and to the State Food Service for a refund. Basically, I will go to the end, if anything I will sue. It's not about money, it's about principle. Due to this attitude towards customers, my feet will never be in this hotel. Although I could follow. year. The owner is a stupid person when he does this.
