Irritated and ****ed of!

If i had it my way i wont even give them one star i took my car for service last Friday which was such a mess up! I told them to pick me up at 15:30 because thats the time i finish work when i called my service advisor at 13:00 i was advised he can't pick me up at that time but if i could leave work a little earlier then they would make a plan otherwise il have to find my own transportation to get there. i tried getting in contact with the dealer just after 13:00 to tell my advisor that they can come earlier for me but unfortunately everytime I called i could not get him on the line and i had to find my own way to the dealership because at four i was told that someone would pick me up and i was not willing to wait! the driver from barons only came to my work place at 16:45. Secondly i asked them to please change the breaks on the car because the front breaks were bad and keep in mind that my car has a maintenance plan and i could hear a knocking noise in the front of the car but I was advised that the breaks were fine and theres nothing wrong with the car and after one week i can still hear the noise on the car and if anything goes wrong i will sue barons!!!!! lastly there is two dents on the driver's side door which wasn't there! I called in last Saturday and spoke to a lady who advised me that the service advisor weren't in which is understandable because it was a public holiday but she assured me that she will give my details for the guy to call me first thing on Monday but it is already Saturday and no one has called me!! I am highly irritated with the fact that my car went in for a service and came back worse than what it was! I never paid for maintenance for nothing but clearly these advisors make it seem like that!!!!
