They will also ban you if you call them out on their bad service and request refunds for wrong/damaged food (and persist even if their CS tries to fob you off, which in an of itself is wrong in my opinion).

I'm assuming they have a per-user metric of overall profit and mine ended up being in the negative so it makes sense from a business point of view. However, I would be worried about their business if they can't properly deliver enough orders to make a profit when someone is holding them accountable.

The business model appears to be based on fobbing the customer off and letting them hold the bag should things go wrong, which is sadly a common thing in large-scale VC-funded startups.
