My complaint:
I already pay $10month for an Uber pass, yet my deliveries are frequently combined with others to keep costs low- however the service fee has only been going up recently. The delivery time is displayed as 20-30 minutes, but after I actually place an order it changes to say latest delivery by (60 minutes from now), and it frequently takes even longer than that.
Suggested solution:
compensate more for delayed deliveries, advertise more realistic delivery times
