Delay on my order

Selected option for my order to be delivered the next day.on the next day no contact was made as to where my order is.Tracked online and it was still not shipped .few days later I track it again and comment was tht I was not available to accept my delivery.why would you deliver on a day not arranged for and still still not do any contact.Am angry how this was handled.i want my order be deliver tomorrow and my account be credited with the difference as you charge differently based on delivery requests duration.
