ELNA Centre de dépistage COVID-19 - Vieux Montréal

Very bad experience, their staff are careless and dereliction of duty. I made an appointment for today's Rapid Antigenic Test for my parents, because the flight is tomorrow morning, so I did the test at 9:45 today, at ELNA Guy1538, Sherbrooke O, Suite 519. Afterwards, the staff told me that the result will be sent to me in 3 hours, but it has not been sent by 7 pm. The plane at 8 o'clock tomorrow morning needs a nucleic acid certificate to board the plane. I don't know what to do now, all my plans have been disrupted, and there is no way to make an appointment with another clinic, because the nucleic acid test is valid within 48 hours. I really doubt that their staff is serious and responsible, are they professional?Very disappointed.
