TRIP.COM — Flight ticket refund

I booked a ticket from Trip.com from Cairo to San Francisco on February 2 2022 on Qatar Airways. At the counter they did not let me in as they said my PCR is valid for one day only which will end one hour before the departure. I went back frustrated called customer service in Qatar airways and Trip. Com . Both are useless . I talked with customer representative of trip . Com for a refund he said he will contact Qatar airways for a refund then he sent an email saying that no refund as the passenger. Me did not show up. I went to Qatar airways office, employee said that they should have send a note and a refund . That means they are not saying the truth and their policy in Qatar airways is refunding because of Covid . I had to issue another ticket with a penalty and increase price of ticket in order to go back . I lost money, time, problems in work, stress and lots of troubles due to their unclear an email.
