Quick to take my money but slow on delivering GREAT SERVICE

Bought a washing machine on Sunday, Arranged for it to be delivered on Tuesday and on the system the lady that assisted put in between 3-4pm as my wife was available after 3pm. My wife then took off from work to accept the delivery however the guys had called me not my wife and wanted to deliver at 11am,Apparently i am the first on route. I then told the guys that i am only available after the stipulated time and was told okay they would deliver then. I then called the guy again at 5pm to confirm what's going on and i was told to speak to his boss Nathan,Nathan then said that they can deliver as it was too late? Please can someone explain however do yourl run a business like this, My wife was only available on that day, She came home early and on top of that Nathans driver said he would deliver later that day. Nathan also said that you guys should have given me a time so I'm confused as to whats going on,This is unacceptapple.... I want answers as you guys are wasting my time
