The app is glitchy at the best of times. There is the issue of when you put in for a same day delivery it will accept your order then unexpectedly it will be canceled. When you call customer service they will advise you to make another order send in your order number to them so they can send it to their verification team. Of course your order will come the next day. And of course you will have spent your total ticket amount twice (previous order+new) before you will recieve your refund.
