What is wrong with hairdressers?

no offense to the hairdressers here, but wow I have had like 5 crappy haircuts in a row. Can no one in my city cut hair?! I have gone to a bunch of different places and I have never got an amazing, actually good looking haircut. 3 days ago (after much deliberation) I finally decided to just go for it a get a full bang (like one that goes all the way across my forehead) and it looks terrible. The bang looks good on me (I surprisingly suit it) but it looks like crap. This is because:
1. She chopped my ends and it looks like someone hacked it with safety scissors
2. she didnt even try to fix my bang that my previous hairdresser screwed up (of course)
3. she took like 10 min to cut my hair and it would have only taken like 3 min if she wasnt helping another custumer while I waited in the chair.
3. She didnt even wash my hair
4. she didnt even wet it so she could cut it properly
5. she straightened my hair so quickly it was a frizzy, unstraight mess
6. she didnt put ANY product in my hair (NOT EVEN WATER!)
seriously I need answers. I shouldnt have to feel so nervous about getting my hair cut, I should be able to trust hairdressers. I mean like their job is that hard! Sorry if I am offending any hairdressers here, but seriously you know Im right! btw my hair kind of looks like Miley Cyrus new bangs cut (not as nice though) Also I got my hair cut at a good place. Its like one of the most high end salons in my city and my cut was not cheap! I am sooo disapointed..
