Update. Otto's apologized and reached out. They also fully credited my order! Updated my star rating to reflect this good service. I will try them again.
Not impressed. We ordered 2 boxes and both came without any sauce or feta (paid extra as well!). I get it that sh@t happens, but on both? To top it off I forwarded my Foodora receipt along with pics of what we got to Otto's email and never even got a response.
