RESERVATION

Dear sirs,
I have reserved a flight for 5 persons from XIAN to CHENGDU today for Tuesday 5th August; the website has asked the names and the n° of passports. I had a confirmation on the screen but I did not receive any mail. The site did not ask me to pay anything.
Could you tell me if everything is ok or if I have to do the reservation again?
My name is: VALOTAIRE; we are 5 persons : VALOTAIRE FRANCKIE, VALOTAIRE FLORENCE, VALOTAIRE LEONIE, VALOTAIRE APOLLINE, VALOTAIRE EVE.
Thanks a lot
