Uber Eats Robbing Customers

Uber eats is rending ********* practices. I placed a order this Sunday.After they took the full payment for it...they then say the item is out of stock for 1 item and the other item they change the flavor without my consent.I called the retailer privately and they do have the item in stock.2 out of 3 things I ordered was not going to come and it was pointless even placing a order with them,They don't have the option to make you cancel the order!It's not the first time they **** and said products are not in stock when they were.They do this all the time in the last minute..My biggest issue is that it's 3 days later and they have not refunded the money for the item that was apparently out of stock.Terrible customer service.
