Manager at this place has no customer service ettiquet! Lost loyal clients due to his attitude

So I am continuing from where I left off last week, I went to VW Constantia, around 12 Saturday afternoon to see if I can speak to the manager DEON, When we arrive we walk in knock on his door and greet to my and my husbands surprise this man tells us he has no time to see to us today as he is busy with commission structures. I lost it I asked him so I am driving without a disc and an expired permit since April, I paid for the disc but no you have the nerve to tell me you have no time to see me today and when I call you hardly ever available when you do answer you forever waiting on someone to get back to you. The attitude from this man on Saturday was the pits! When I asked what does he have time for he said not this right now as he has written us down on his white board in red and we should have waited for him in the waiting area with a cup on coffee, imagine ive been waiting since Dec for my disc I go out of my way on a Saturday to get some answer very politely to get **** from this man. Says the best he can do is give me another permit I said no I want my disc because how long will I have to wait for the disc once I accept the permit I paid for the disc, Deons response, well he has to pay R350 for this permit also I asked Deon is that my problem which he response no it is not but its the best he can do now. Not long the sales rep runs in and says they have the disc so now Deon goes off at him infront of me (the client) asking why was he never informed now for me that is an internal query I AM THE ****EN CLIENT AND I RECEIVED ATTITUDE FROM THE MANAGER AT THE USED CAR SIDE, we have been with the same dealership since 2015 all our cars are from this dealership but let me tell you something today you have lost 2 loyal clients because of bad customer service from the Manager at the used car side, it might not be much but we buy top of the range VWs from new and used car section, this was the last from myself my husband or any family member or friend as I have referred many in the past but this was ****ty service! Deon I hope that VW head office sends you for some customer service training if they do not want to lose any more clients, Saturday your attitude towards me was disgusting to say the least, you should be ashamed! I still have not received my spare keys from this dealership and will be writing to VW head Office on this as I am done running after things that I have financed!
