Sat for a half hour attempting to pay for my order. Charged then instantly refunded. Two payment methods even! Now I have to go in. I won't get the deals, so only ordering half the food. I use fast food apps frequently, and this one is obviously flawed. First and last time for a while. It looks like you guys need a lot more development time if you can't accept either form of payment on an already, ong time developed app, from a massive corporation. Pretty surprising for "Burger King".
