Ubereats

Twice in one week I have placed an order on UberEats and the money has been deducted from my bank account only for the order to disappear off my ubereats profile and not be delivered. When I contacted the restaurant I ordered from they said they had not received the order. There is nowhere on the ubereats app to contact anyone for an explanation. I will no longer be using ubereats. I'll rather just order from the restaurant directly for their delivery or pick it up myself. Terrible service from UberEats.
