Bad Service, Bad communication

Last year October, i took my car for a major service, and they said they will communicate with me if there was any additional things i will need to do. They didn't, i had to call them to find out what was going on, that's when they sent me an email. When i collected my car later on, it wasn't even washed, they couldn't even be bothered that it's not washed, i had to complain for them to decide to wash my car. Now this year i decided to go back to them, i went yesterday for something i needed them to do in the car, they said they will check the car and come back to me, and asked me what was my budget, i told him R4000, then he said before he does anything extra, he will contact me, which he never, instead i had to call later yesterday to find out what was going on, then he told me the things his added without my permission , i let go of that one, i chose to not make a big deal about it, then they had said that they will collect me at 9am, today, since 8:45am i was trying to call them to find out if they will be here at am9am, only at am10:20am that's when i got hold of them, by then was late because i had .to cancel my appointment because i didn't know what was going on.
