Food Panda — did not receive order even after online payment multiple times

Hello, I had used Food Panda to order a few items even before. But for a couple of times I have not received my order. The order is accepted as my money is being paid and kept in preparation for hours. This has happened more than a couple of times. There is no way I can register a complaint on their site, so I have to register it here.
I have been cheated more than once in this manner, wait for the person to get tired of the order and then I checked in my order list, all my orders are said to be delivered. Also their support is only a chat bot, which is hard to navigate too.
