Agoda Wrong Reservation Dates – Request Full Refund of $254.78

I made a reservation through Agoda for Eurostars Ambassador and clearly intended to book the dates 5–6 September. However, the system ended up booking 12–13 October instead. When I noticed this mistake, I tried to at least modify the dates even if it required an additional payment, but the platform did not allow any change. Since I urgently needed accommodation for the correct dates, I had to book another hotel via Booking.com. I then cancelled the incorrect Agoda reservation, but instead of a fair solution, I was charged a full cancellation fee of 254.78 USD and received 0 EUR refund. I also tried to reach Agoda customer support, but no one replied to me or explained how they intended to handle this issue. I find this situation and the lack of support unacceptable. I request a full refund of the 254.78 USD cancellation fee that was charged for this reservation, as the date mismatch and the impossibility to modify it have caused me both financial loss and significant inconvenience.
