Stupid bloody work- and delivery-men

I HATE fucking workmen and fucking delivery men. Why can they never do as they say they're going to do? Why? Why must they do this? So many times now I have waited in ALL day for some sort of delivery or engineer, only for them not only not to come on time, but not even to come at all! And even worse, sometimes they say they DID come, but that you must have been out! Why would they even say that? When you've been sat there all day, not really doing anything, waiting, wasting your life for them, in order for them to do some tiny thing that'll probably only take half an hour. How many human hours must have been wasted in this way, with people all over the globe sat in their houses, looking out the window occasionally, wondering why "between 9 and 12" always seems to mean "maybe by 5 if you're lucky, if at all, if we feel like it".

And of course you can't ring them up and ask where they are, because if you ring too early they'll just say "well they can come any time up until [insert made up and unlikely time here]". So you have to wait, and wait, and wait, until it's 5pm and you KNOW they're not coming, and then you ring them (or wait until the next day because unfortunately our office is now closed, office hours are BLAH to FUCK) and they say "oh yes, they didn't come. Can you be in next Tuesday between 6am and 11.33pm?" DON'T THEY REALISE PEOPLE HAVE THINGS TO DO IN THE DAY?????????????? ARRRRRRRRRRRRRRRRRRRRGGGGGH!

Death to all workmen, death to all delivery men, death to anyone who comes anywhere near me and my crimson glare of death in the next half hour.
