Changes delivery times without notice.

Selected Friday as delivery day. Or would have selected and paid for an earlier day. Showed would be delivered on the Friday. So I cancelled all. Meetings and errands for Friday.. Friday at 12pm. It changes to delivery before 7pm.. So now I cannot even make plans after 5pm while waiting all day. No correspondence on changes or possible changes.. Just shows on the app change in times.

My entire day was gone.
