audi claremont bad service and inexperience mechanics

Hi booked my vehicle in at audi claremont for a thursday morning service advisor said you vehicle booked for 7am please make sure its there at 7am .i dropped off vehicle the tuesday already so it can be early for thursday morning at 7am.i asked to speak to workshop forman to inform him what must be done on vehicle he didnt let me finish and cut me short and said whats the problem in reply i was shocked that he was so abrubt and gave him a short version that the shocks needs to be re oiled and pressurised .i then called thursday at 11 .12 .1 .2 .3 oclock and couldnt get hold of service advisor and his not returning my messages .he then called at 4 and said they diagnosed the vehicle and he must order the oil .oil wil arrive at 9am friday morning and vehicle wil be ready however they only looked at vehicle after 1 .so much for being there at 7am.i then called friday several times with no reply .i decided to drive to audi at 3.30 and on my way service advisor returns my call and says vehicle wont be ready i then stil made my way to audi only to see mechanic only starting on my vehicle with a step by step guide on how to do the job .mechanic then told me they never have done so a job so much for being qualified he then assured me vehicle wil be ready monday once he gets to know how to operate machine.monday came along left several messages again only with a reply after 1 to say vehicle not ready mechanic not in and head mechanic now looking at it .he also has to check vehicle cause his not fami**** of whats happening.hoping to see outcome tomorow .so you think by taking your vehicle to the agents and they dont know what they doing
