Bad delivery service

I ordered a door from leroy merlin, and everything was fine until the delivery day. So on their confirmation email they said delivery will take place 3-5days the following day while at work I saw several missed calls and when I called the number, I found out it was the delivery guy saying he was at my gate about an hour ago,and after blaming me for not answering phone, he said I should expect delivery the following day.

My problem is firstly why rock at the house without notifying me that I should expect my delivery earlier than communicated so that I can make arrangements for someone to be home if I am not there.

Secondly when I called the delivery guy the following day he did not take my 1st 3 calls eventually a woman answered the phone. I asked what time should I expect my delivery she said the guy does not work on Saturdays, which surprised me because he promised I will be getting my delivery on that Saturday.
