I booked the round air tickets online via Flightnetwork firstly on June 3rd, but online showing my reservation had failed, I found my credit card was charged portion of the ticket(only one way), so I called the 1-905-829-8699 to ask staff help me fix or check out. The staff with number 2216 were helping me book the return tickets(one way tickets were paid), he firstly tried to charge fare from credit card with return tickets.but he said my credit card declined.He tried to charged again.then he completed my reservation and send the confirmation.After that, I found my credit card was charged twice and I called my bank to double check the specific transactions.The bank staff told me West Jet charged me twice. Later, I called back the staff from Flightnetwork, he said there is only one charge showing there, now I were sad.So now I just am waiting my E-ticket from Flightnetwork and waiting the my credit card transaction showed on my website bank about 2-3 days and email to Flightnetwork to prove it, which can solve the problem. After that, I thought a lot, I think the Staff 2216 made mistake when helped me book return tickets, I remember when he said my credit card declined firstly, he told me wait me a while, and I ask him to I wanna change to use Mastcard for paying, but later he said wait, I put your reservation on it, then he said it is ok now, booked it. I said really? I do not need change into MasterCard? He said he complete the reservation, I trust him what he said. After I checked my current available credit online, It was charged double money！！So I call my bank and staff told me specific transaction about West Jet charged twice from my credit card and it was US dollers!Crazy! till now, I received my E-tickets today and itinerary that the 2216 staff send to me, I look over whole document, I realize I can not find my receipt of payment for return tickets with West Jet, I do not know what exactly I paid, Staff from flightnetwork and online said only $847.74 CND.But I do not have proof to check!that is suck!I can't believe the Flightnetwork anymore, I will learn the lesson !JUST WANNA THE STAFF FROM CUSTOMER CARD DEPARTMENT CAN CONTACT ME RIGHT NOW AND SOLVE THE PROBLEM !
