Brought my card for service but they damaged it

I have received the most pathetic service from sales agent (Denver Solomos), service agent (Shazana Lee (she doesn't even bother to respond to my email) and the workshop team. I brought my Kwid in for its service on 26/11/2019 but their workshop team ruined my car, not once.

1. They broke the fuel cable 2 They damaged the window on the driver's side .

I found out myself when got to the fuel station. I couldn't open the fuel tank. They fixed it but when got home again tried to open the window on the driver's side but I couldn't. The window doesn't open. I told them them from the beginning when I'm leaving Cape Town for holidays.

Still waiting for their response.
