Agoda Confirmed Hotel Reservation but No Room Available Upon Arrival

I made a fully paid and confirmed reservation through Agoda for Business Life Hotel & SPA Bakırköy, with stay dates from 5 to 11 October 2026. The reservation was made about six months in advance and I have a confirmation with ID 640997899 stating that the booking was paid and guaranteed, with a total cost of 183.94 €. When I arrived at Business Life Hotel & SPA Bakırköy on 5 October 2026, the hotel informed me that they were fully booked and had no room available for me, despite my confirmed and prepaid reservation via Agoda. Because of this, I was left without the room I had booked long ago and had to accept an alternative hotel arranged on the spot. The alternative hotel provided was of clearly lower quality compared to the hotel I originally booked. There was no hot water in the shower, the food was very poor, and the general conditions did not match what I had paid for and expected. I also informed the staff about these problems, but nothing was done to improve the situation. I am extremely dissatisfied that, after paying six months in advance and receiving written confirmation from Agoda that my reservation was paid and confirmed, I was sent to a low-quality hotel with bad conditions. This situation is not my fault, and I should not be the one to suffer the consequences of overbooking or mismanagement between Agoda and the hotel. I request that I be moved to my original hotel, Business Life Hotel & SPA Bakırköy, for the remaining nights of my stay, or, if this is not possible, that Agoda refund me in full the amount of 183.94 € for the original reservation. In addition, I request that Agoda cover the cost of my current accommodation until 11 October 2026, as I should not be paying for an inferior stay when I already paid for a better hotel months ago. I kindly ask Agoda to review this situation urgently and provide a fair and fast solution.
