Kiwi.com complaint: Removed from the flight

My name is Olha Sirenko. I am Ukrainian.My family forced to leave Ukraine because of the war, my husband and your father are still in Ukraine and unable to leave, we live in the UK under the Homes for Ukraine scheme, my mother is having to work to pay for your family needs,and we are supported by the local foodbank .
I am writing all this to explain the situation that has happened with in the airport.
I had a flight from 17th of August till 23rd of August.( Bristol-Barselona-return Barselona-Bristol). When I booked my flight, I added all passport details and the system sent me the boarding passes.
I have booked a hotel through this site for the period from the 17 till 23 of August. In Bristol airport , during boarding, a representative denied us the trip as my daughter’s passport expires in two months. I am certain that the airline was aware of these regulations but still sold us tickets, knowing in advance that our flight wouldn’t take place. I have to stay at Bristol hotel this day because it was to late and we live far away.This also cost me a significant amount of money. Besides the hotel in Spain which I have booked , didn’t want to make me a refund. I kindly ask you to help me with this problem, because this is a big amount of money for my family and I trip was ruined.
Waiting for your soon reply
Regards, Olga
