Delivery expected at 11, only delivered after 4pm

I have meeting to attend, I arranged my day to suit the courier company so they could deliver between 11-12am on Monday 20 April. I got a phone call at about 1230, saying they were late and would deliver by 2. After several calls (many of which I was kept on hold for), and some firm talking to they delivered the card at 4pm. Not acceptable at all. I shouldn't have to shout at a supplier to get a job done.
