Poor service

I ordered a spare key in April 2019 and I have been dealing with Danie that knows nothing about TCF (Treating Clients Fairly). They ordered me wrong spare but I was told that when I got to the dealer. Then I was told they will call me once they have the correct cut. Waited for 2 weeks and there was no communication. I called again spoke to a guy who's worst than Danie.... That guy is full of empty promises. Had to contact the dealer where I bought the car from to speak to Hatfield VW Rivonia. Eventually there was a movement.... Danie called me saying I must bring the car to them so he can check what's the problem with the lock. Which I did on the 24th of June (mind due the spare key was ordered in April). On the 24th of June I got to their dealer before 7am but still the matter was not resolved Danie did not even communicate with like they do when you take your car in for service. Then I when I call in I was told Thulani will call me which he did.... Apperantly they have got the key from their hub in centurion but the key does not turn I must still take the car to them on the 25th June.... What service is this?. Told Thulani I cannot because I didn't have a car on the 24th so I need to cover my errands.... He promised to meet with me in Kensington, I must call him and confirm of which I did. I called him at 8am telling him that I'm gonna be in Kensington from 9am til 14h00.... He said okay send me location, which I did. But no he didn't.... Called him at 13h00 he didn't answer. I left then he responded that his drive is on his way. The driver called saying he have arrived. Told him everything and he understood everything then he said he will call me on the 26th of June but HE DIDN'T. I don't know what to do know..... I AM NOT TREATED LIKE A VALUED CUSTOMER. THAT TIME BOUGHT THE CAR AT 16000KM
