Do what your hired for?

Today was my 1st 15000km service since I bought the car at Mazda Wonderboom , what i experienced when I went to collect my car after service is Bad service + attitude. im a client and expect to be dealt with in a professional and respectful manner , I came in to collect my car I found the theron guy playing with his cellphone ,I greeted him and he didn't respond ,I told him and there to collect my car he ask me the surname and looked on the colleagues table and he went out to go collect the keys and he gave me the keys together with the receipt and told me my car is outside .I asked him where outside he said outside (with attitude) and he went at the back ,there were two gentlemen on the boom and the other guy cleaning the floor ,I ask the cleaning guy 1st that if a person give me the keys and doesn't show me the car what do u call that and he was also shocked and told me that not how the consultants do, I asked the guys by the boom they were also surprised the other 1 took my keys and asked me for the car reg to go look for the car he couldn't find it and told the theron guy who told me he didn't take in my car in the morning so where must he find it. I need someone to contact me
