Headlights not working

I have a bad service from the person who was assigned as my service advisor by the name of Elias . My Car was towed to the dealer on 23.11.2024 after it failed to start when trying to change headlights bulbs. It was on a saturday . Elias only called me on 26.11.2024 to ask what is wrong with the car and I then explain that the car failed to start when trying to change headlights bulbs- it was 2 issues ( Non starter and headlights not working). He said he need a go-ahead from for the technicians to start with the work but I will be liable to pay over R3000.00 . I said it is fine because I was desperate for the car to be fixed and mind you the car is still under warranty. On the 28.11.2024 (Thursday) Elias called again to confirm that the car is fine I can come and fetch it and amount I must pay is R3105.00. I confirm to go the next day which was the 29th november 2024 . When I arrive it was after 17h00 , Elias gave me an invoice to go and pay . I went to the cashier to pay and gave him the receipt , he then handed me the car key and went out with me to the car. The car was starting which I was happy with . I ask Elias to switch on the headlight and it was still not working . He then said it is after hours I must bring back the car . I went again on 02.12.2024 I was not okay at all he didn't even show sympathy or that he is willing to assist , he was not helpful at all , he then said the car must be booked, they gave booking for 04.12.2024 . I took the car back I request to have a new service advisor . The new service advisor said she will call during the day , she did call and told me that the problem with headlights is a switch and is not available in store . They will order one for me and will contact me once it is available . I was not given any turnaround time. I called again on 11.12.2024 and same story that I will be contacted. Now I am sitting with a car that I cant even use because when I come back from work is already late and headlights are not working . This is costing me a lot of money using public transport and paying for the car instalment that is still under warranty and not receiving any joy from dealership. On the 17th december I have to travel to Limpopo to visit my mom and this does not seem to be possible. I did ask Elias about courtesy car the 1st time the car was there and he said I can not qualify for one. I just need assistance for the headlights to be fixed so that I can go on with my life and have peaceful sleep
