Very Unhappy Client

I'm a very unhappy client, I've booked a flight online using the Shoprite option, been to the Shoprite to pay, in an out a few times because they couldn't assist me because they offline, I tried to pay my booking for 2 days, and just lost the tickets and booking because the 48 hours expired. <br> I have lost my Mango Flight Booking because of Shoprite being offline and couldn't assist me. I also tried to change my payment options from Shoprite to jet only to find out cant be done like that.<br> I've always used mango and never had this happened before so im very unhappy, now I need to make a new booking with a higher price range. When u make an online booking and the place where u pay is offline Mango should send a email to the client stating other payment options. I blame both Mango Airlines and Shoprite for the booking being cancelled. Very unhappy Client.
